In the second step. Nitrogen (the element) has 7 electrons. In conclusion, Hydrogen's positive end joins oxygen's negative end. ACS Catal. It is pyruvate production from neutral glucose that generates H+: Although the reaction glucose 2lactate + 2H+ releases two H+ when viewed on its own, the H+ are absorbed in the production of ATP. This problem has been solved! What kinds of organisms use anaerobic cellular respiration? Count all of its lone pair electrons, and half of its bonding electrons. Muscle cells and red blood cells make the most lactic acid, but it can come from any tissue in your body. During this time, he worked at the University of Lille, where a local distillery asked him for advice concerning some fermentation problems. IT IS FOR 3D PRINTING name of the chapter chemical reactions and equations case based mcqs clean magnesium ribbon about cm long rubbing it with sandpaper. Lactic acid produced by fermentation of milk is often racemic, although certain species of bacteria produce solely D-lactic acid. In order to be able to draw the Lewis structure for a given molecule, you need to know how many valence electrons it contains. Direct link to Ivana - Science trainee's post aerobic respiration proce, Posted 5 years ago. [15], Lactic acid fermentation is also used in the production of sauerkraut. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Characteristics of Valence Electron. 3- why carbon atom has the ability to form many organic compounds? . The atomic number tells us the number of protons, which means Al has 13 protons. So once the use of ATP is included, the overall reaction is. [35] The study "provides novel data on biphasic NAD(P)H fluorescence transients, an important physiological response to neural activation that has been reproduced in many studies and that is believed to originate predominantly from activity-induced concentration changes to the cellular NADH pools. Across the suborbital, the electronic configuration of chlorine is 1s 2 2s 2 2p 6 3s 2 3p 5. Image of tanks used for wine production by fermentation of grapes. The difference is more pronounced in chickens and grouse (see figure below), which stand around all day on their legs. Arsenic has 33 electrons around its nucleus, 5 of which are valence electrons on the outermost orbital. [40] If this is the case then the calculated food energy may use the standard 4 kilocalories (17kJ) per gram that is often used for all carbohydrates. [45], As a food additive it is approved for use in the EU,[46] USA[47] and Australia and New Zealand;[48] it is listed by its INS number 270 or as E number E270. Although glucose is usually assumed to be the main energy source for living tissues, there are a few reports that indicate that it is lactate, and not glucose, that is preferentially metabolized by neurons in the brain of several mammalian species (the notable ones being mice, rats, and humans). Bifidobacterium bifidum utilizes a lactic acid fermentation pathway that produces more ATP than either homolactic fermentation or heterolactic fermentation: Some major bacterial strains identified as being able to ferment lactose are in the genera Escherichia, Citrobacter, Enterobacter and Klebsiella . The Lewis Structure also shows that it is a polar molecule since all of the electrons are not evenly distributed. The remaining #4# valence electrons will be placed as lone pairs on the sulfur atom. It is also possible to encounter a molecule that seems to have too many valence electrons. You may have notice this type of fermentation in your own muscles, because muscle fatigue and pain are associated with lactic acid. This leaves 28 unpaired electrons in the inner orbitals. Answers: 1. We have formal charges on this carbon. The complexity of organic chemicals is due to the tetravalent carbon atom which, with four valence electrons, is capable of bonding to four other atoms. Most lactic acid is vegan, as it primarily occurs during the natural fermentation process of plants or is man-made using plants. Alcohol fermentation has two steps: glycolysis and NADH regeneration. Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid ( C 3 H 6 O 3) (see figure below . Valence electrons are the electrons in the outermost shell of an atom. How many protons neutrons and electrons are in Al 27? Even if Pasteur didn't find every detail of this process, he still discovered the main mechanism of how the microbial lactic acid fermentation works. As far as I am informed, it does not cause great damage but due to heavy accumulation inside cytosol (as a result of excessive work and anaerobic respiration), it causes muscle strain. [1], Lactic acid is a component in the production of sour beers, including Lambics and Berliner Weisses. Add or subtract electrons if the structure is an anion or cation, respectively. There are two shells of selenium with eight electrons each: 2, 8, 18 and 6. How can I draw a Lewis structure of a compound. These bacteria can also grow in the mouth; the acid they produce is responsible for the tooth decay known as caries. A valence electron is the total number of electrons found in a valenceshell. Legal. Exclude groups 3 through 12. Eliezrie, Inc., manufactures and sells two products: Product G8 and Product O0. 8 B. The resulting lactate can be used in two ways: However, lactate is continually formed at rest and during all exercise intensities. Count all the valence electrons for each atom. thermophilus (Streptococcus thermophilus). Success of lactic fermentation was most evident in yogurt cultures. Direct link to Ivana - Science trainee's post *Good question* During the 1990s, the lactic acid hypothesis was created to explain why people experienced burning or muscle cramps that occurred during and after intense exercise. While not normally found in significant quantities in fruit, lactic acid is the primary organic acid in akebia fruit, making up 2.12% of the juice. On this Wikipedia the language links are at the top of the page across from the article title. 3. The bacteria produce lactic acid, as well as simple alcohols and other hydrocarbons. In 1857, the French chemist Louis Pasteur first described lactic acid as the product of a microbial fermentation. There are 14 neutrons and 13 electrons in Aluminum-27. Lactic acid created as a byproduct of fermentation of pyruvate from glycolysis accumulates in muscles causing a burning sensation and cramps. You may have not been aware that your muscle cells can ferment. How many valence electrons are in a silicon atom? Going from pyruvate to ethanol is a two-step process. In solution, it can ionize by loss of a proton to produce the lactate ion CH3CH(OH)CO2. Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid \(\left( \ce{C_3H_6O_3} \right)\) (see figure below) and regenerates NAD\(^+\) in the process, allowing glycolysis to continue to make ATP in low-oxygen conditions. TiO2 exists naturally in three crystalline forms: Anatase, rutile, brookite, and TiO2 (B). it has four valence electrons. Fermented milk products are obtained industrially by fermentation of milk or whey by Lactobacillus bacteria: Lactobacillus acidophilus, Lacticaseibacillus casei (Lactobacillus casei), Lactobacillus delbrueckii subsp. Recall that glycolysis breaks a glucose molecule into two pyruvate molecules, producing a net gain of two ATP and two NADH molecules. Major genera of lactose-fermenting bacteria, "Fermented Fish Products in the Philippines", "Lactic-Acid-Fermented Fish and Fishery Products", "Lactate, not Lactic Acid, is Produced by Cellular Cytosolic Energy Catabolism", https://en.wikipedia.org/w/index.php?title=Lactic_acid_fermentation&oldid=1142350192, Wikipedia articles needing page number citations from August 2019, Articles with unsourced statements from March 2021, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 1 March 2023, at 22:50. The definition of lactic acid is "an organic acid (C 3 H 6 O 3) present especially in muscle tissue as a by-product of anaerobic glycolysis, produced in carbohydrate matter usually by bacterial fermentation, and used especially in food and medicine and in industry.". Lactic acid containing bacteria have shown promise in reducing oxaluria with its descaling properties on calcium compounds.[39]. When hydrolysis is performed by hydrochloric acid, ammonium chloride forms as a by-product; the Japanese company Musashino is one of the last big manufacturers of lactic acid by this route. The valence of oxygen is also constant and equal to two. All four of these groups fall underneath the family of Enterobacteriaceae. A: Given : mass of solute ( KCl ) = 5.80 g Molality of KCl solution= 0.160 m = 0.160 mol / kg. Lactic acid is used in some liquid cleaners as a descaling agent for removing hard water deposits such as calcium carbonate, forming the lactate, calcium lactate. How many valence shell electrons are in the molecule CCl4? It is because of the dominance of this mutation that Western cultures believe it is unusual to have a lactose intolerance, when it is in fact more common than the mutation. As a result, neutral helium will only have 2 electrons surrounding its nucleus. [22], Lactate fermentation is important to muscle cell physiology. The molecule ow many valence electrons doing an intense workout, and carbon., oxygen has 6, and, each hydrogen how many valence electrons does lactic acid have one proton each. These polymorphs exhibit different properties and consequently different photocatalytic performances. Consumption of these peaks during cultural festivities such as the Mongolian lunar new year (in spring). . Or between the two types of runners? A mixture of the two in equal amounts is called DL -lactic acid, or racemic lactic acid. One is known as L -lactic acid, ( S )-lactic acid, or (+)-lactic acid, and the other, its mirror image, is D -lactic acid, ( R )-lactic acid, or ()-lactic acid. It can also form different types of chains. Direct link to Revan Rangotis's post Okay, this is actually re, Posted 5 years ago. In animals, L-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise. We looked at the potential producti Direct link to Ivana - Science trainee's post As far as I am informed, . The tanks are quipped with pressure-release valves. The AX4 geometric shape is then known as a tetrahedral. Allison Soult, Ph.D. (Department of Chemistry, University of Kentucky). The name of the derived acyl group is lactoyl. [50] Lactic acid is produced commercially by fermentation of carbohydrates such as glucose, sucrose, or lactose, or by chemical synthesis. Swedish chemist Carl Wilhelm Scheele was the first person to isolate lactic acid in 1780 from sour milk. Types of reaction: Condensation - Removal of water. Transcribed image text: NH2CH2CO2H glycine 1. number of valence electrons: Lewis Structure Molecular Geometry Drawing 2. central atom (s): 5. molecular geometry: 3. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Muscle cells also carry out lactic acid fermentation, though only when they have too little oxygen for aerobic respiration to continuefor instance, when youve been exercising very hard. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. For example, some archaea called methanogens can use carbon dioxide as a terminal electron acceptor, producing methane as a by-product. SO42-. During power exercises such as sprinting, when the rate of demand for energy is high, glucose is broken down and oxidized to pyruvate, and lactate is then produced from the pyruvate faster than the body can process it, causing lactate concentrations to rise. Let's take a closer look at what valence electrons are and how they contribute to an atom's properties. When that happens, we expand the valence shell of the central atom. The terms " oxidation degree " and " valence " may not be the same, but they are numerically almost identical. Other products, like industrial yogurt, coming mainly from China and western countries, have tended to replace it more and more, mainly in urban areas. bulgaricus (Lactobacillus bulgaricus), Lactobacillus helveticus, Lactococcus lactis , Bacillus amyloliquefaciens, and Streptococcus salivarius subsp. "[36], Lactate can also serve as an important source of energy for other organs, including the heart and liver. This means that the molecule will have a total of #8# valence electrons. [3] Sometimes even when oxygen is present and aerobic metabolism is happening in the mitochondria, if pyruvate is building up faster than it can be metabolized, the fermentation will happen anyway. Find out more with BBC Bitesize. To determine the valence electrons of nitric acid we have to follow two steps. In which of the following sets is the symbol of the element, the number of protons, and the number of electrons given correctly? The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. To find formal charges in a Lewis structure, for each atom, you should count how many electrons it "owns". A molecule of nitrogen trichloride contains one nitrogen atom and three chlorine atoms. Each chlorine atom will complete its octet by adding #6# other valence electron as lone pairs. Score: 4.9/5 (8 votes) . The generation of CO2 during respiration also causes an increase in [H+]. 2023 Feb 7;13(4):2681-2695. doi: 10.1021/acscatal.2c05690. Once we know how many valence electrons there are in PH3 we can distribute them around the central atom and attempt to fill the outer shells of each atom. http://www.tempeh.info/fermentation/fermentation.php, http://www.tempeh.info/fermentation/rmentation.php, status page at https://status.libretexts.org. By Bel Kirsten On Oct 26, 2022. The cells then default to fermentation, since they are in an anaerobic environment. For long periods of time, they carry out aerobic respiration in their "specialized-for-endurance" red muscles. FIELD OF THE INVENTION. c.two valence electrons are shared. Most commonly, this is produced naturally by various strains of bacteria. Or how your muscles keep working when you're exercising so hard that they're very low on oxygen? Lettuce and cabbage were examined to determine the types of lactic acid bacteria that exist in the leaves. 2. In, Fermentation and cellular respiration begin the same way, with glycolysis. The third shell contains seven electrons. Muscle color reflects its specialization for aerobic or anaerobic metabolism. { "15.1:_Glycolysis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.2:_The_Citric_Acid_Cycle" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.3:_Lactic_Acid_Fermentation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.4:_The_Electron_Transport_Chain" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.E:_Metabolic_Cycles_(Exercises)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.2:_Homeostasis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_10:_Nuclear_and_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_11:_Properties_of_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_12:_Organic_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_13:_Amino_Acids_and_Proteins" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_14:_Biological_Molecules" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_15:_Metabolic_Cycles" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_1:_Measurements_and_Problem-Solving" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_2:_Elements_and_Ions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_3:_Compounds" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_4:_Structure_and_Function" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_5:_Properties_of_Compounds" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_6:_Energy_and_Properties" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_7:_Solids_Liquids_and_Gases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_8:_Properties_of_Solutions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_9:_Equilibrium_Applications" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "Lactic Acid Fermentation", "showtoc:no", "license:ck12", "authorname:ck12" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FUniversity_of_Kentucky%2FUK%253A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)%2FChapters%2FChapter_15%253A_Metabolic_Cycles%2F15.3%253A_Lactic_Acid_Fermentation, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Lactic Acid Fermentation: Muscle Cells and Yogurt. These may then combine to form esters, contributing to the unique flavor of sauerkraut. For calcium, which has an atomic number of 20 and therefore 20 electrons, find calcium on . Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. Short spurts of sprinting are sustained by fermentation in muscle cells. why plants can not regenerate pyruvate from ethanol? The number of valence electrons of an atom can be obtained from the periodic table because it is equal to the group number of the atom. Therefore we only have 8 valence electrons for the H3O+ Lewis structure. Blood sampling for this purpose is often arterial (even if it is more difficult than venipuncture), because lactate levels differ substantially between arterial and venous, and the arterial level is more representative for this purpose. Per chance and with the badly equipped laboratory he had at that time, he was able to discover that in this distillery, two fermentations were taking place, a lactic acid one and an alcoholic one, both induced by microorganisms. Apart from whole-sequence genomics, common tests include H2S production, motility and citrate use, indole, methyl red and Voges-Proskauer tests.[9]. Because carbon atom has 4 valence electron and can form 4 covalent bonds with another carbon atom or other different atoms (N, S, O, Cl,). Data concerning the expected production of each product and the expected total direct labor-hours (DLHs) required to produce that output appear below: Use this method to predict the charges of ions in Ionic compounds a step! If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen. The valence is a numerical characteristic of the ability of atoms of a given element to bond with other atoms. 27 febrero, 2023 . Direct link to Angela's post The article states that r, Posted 6 years ago. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH. Best Answer. A hydrogen sulfide molecule, #"H"_2"S"#, contains two hydrogen atoms and one sulfur atom. This factor may have given them an important advantage to out-compete the hunter-gatherer societies. The next atom, lithium, has an electron configuration of 1s 2 2s 1, so it has only one electron in its valence shell.Its electron dot diagram resembles that of hydrogen, except . It is found in small quantities in the Earth's crust and is thought to have properties that are both beneficial and harmful to human health. 2 c. 4 b. In helium's case, both its electrons will be valence electrons. One is known as L-lactic acid, (S)-lactic acid, or (+)-lactic acid, and the other, its mirror image, is D-lactic acid, (R)-lactic acid, or ()-lactic acid. In contrast, 36 ATP molecules can be generated per molecule of . Advertisement. But even Pasteur himself wrote that he was "driven" to a completely new understanding of this chemical phenomenon. During NADH regeneration, the two NADH donate electrons and hydrogen atoms to the two pyruvate molecules, producing two lactate molecules and regenerating NAD+. Although humans are obligate aerobes (an organism which requires oxygen for cellular respiration), our muscle cells have not given up on ancient pathways which allow them to keep producing ATP quickly when oxygen runs low. Lactic acid is chiral, consisting of two enantiomers. In addition fluorine is very reactive so would not exist by itself for very long. In, 49 protons, 49 electrons c. Cs, 55 protons, 132.9 . Neither lactic acid nor lactate causes muscle soreness. Do you consider yourself a sprinter or a long distance runner? He was the first to describe fermentation as a "form of life without air. Such "sprinting" flight depends on anaerobic respiration in the white cells of breast and wing muscle, allowing rapid production of ATP in low oxygen situations. 3: Lactic acid, C 3 H 6 O 3. These bacteria ferment sugars into acids, unlike the yeast that ferment sugar into ethanol. This paper aims to clarify the differences between It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells. When the orbitals overlap along an axis containing the nuclei, they form a bond. Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. A mixture of the two in equal amounts is called DL-lactic acid, or racemic lactic acid. Lactobacillus fermentation and accompanying production of acid provides a protective vaginal microbiome that protects against the proliferation of pathogenic organisms.[20]. Direct link to tyersome's post It is associated with dam, Posted 3 years ago. H2 is not an atom, it is a diatomic molecule. InChI=1S/C3H6O3/c1-2(4)3(5)6/h2,4H,1H3,(H,5,6)/t2-/m0/s1, Except where otherwise noted, data are given for materials in their, H. Benninga (1990): "A History of Lactic Acid Making: A Chapter in the History of Biotechnology". DL-Lactic acid is miscible with water and with ethanol above its melting point, which is about 16 to 18C (61 to 64F). In this article, we'll take a closer look at anaerobic cellular respiration and at the different types of fermentation. Valence Electrons Chart for All Elements.

In 1808, Jns Jacob Berzelius discovered that lactic acid (actually L-lactate) also is produced in muscles during exertion. So it has a minus one formal charge. Some prokaryotesbacteria and archaeathat live in low-oxygen environments rely on anaerobic respiration to break down fuels. The valence electrons for calcium (Ca) are therefore two. In 2006, global production of lactic acid reached 275,000 tonnes with an average annual growth of 10%.[17]. Total electron pairs are determined by dividing the number total valence electrons by two. With the amount of lactose lowered, there is less build up inside of the body, reducing bloating. The atomic number of . It now has 123456 discount. This early habituation to lactose consumption in the first settler societies can still be observed today in regional differences of this mutation's concentration. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. [citation needed] On the other hand, lactic acid produced by anaerobic respiration in animal muscles has the (L) enantiomer and is sometimes called "sarcolactic" acid, from the Greek sarx, meaning "flesh". Direct link to Phil Rattazzi's post Is there a reason why Flo, Posted 6 years ago. It is unclear if further use of lactic acid, through fermentation, in the vaginal canal is present [6], In small amounts, lactic acid is good for the human body by providing energy and substrates while it moves through the cycle.
