Isobutyric acid

Isobutyric acid, sodium salt, 14C-labeled

C4H8O2 (88.0524)


Isobutyric acid is a carboxylic or short chain fatty acid with characteristic sweat-like smell. Small amount of isobutyrate is generated via microbial (gut) metabolism. Small amounts may also be found in certain foods or fermented beverages. There is anosmia (genetic inability to smell) for the odor of isobutyric acid with a frequency of about 2.5\\%. (OMIM 207000). Isobutyric acid is slightly soluble in water but much more soluble in ethanol, ether and organic solvents. Isobutyric acid can affect people if breathed in and may be absorbed through the skin. Contact can irritate and burn the skin and eyes. Breathing Isobutyric acid can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Present in apple, morello cherry, guava fruit, wine grapes, pineapple, crispbread, other breads, cheeses, wines, scallop and several essential oils, e.g. Roman chamomile.

Pyruvic acid

alpha-Ketopropanoic acid

C3H4O3 (88.016)


Pyruvic acid, also known as 2-oxopropanoic acid or alpha-ketopropionic acid, belongs to alpha-keto acids and derivatives class of compounds. Those are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. Thus, pyruvic acid is considered to be a fatty acid lipid molecule. Pyruvic acid is soluble (in water) and a moderately acidic compound (based on its pKa). Pyruvic acid can be synthesized from propionic acid. Pyruvic acid is also a parent compound for other transformation products, including but not limited to, 4-hydroxy-3-iodophenylpyruvate, 3-acylpyruvic acid, and methyl pyruvate. Pyruvic acid can be found in a number of food items such as kumquat, groundcherry, coconut, and prunus (cherry, plum), which makes pyruvic acid a potential biomarker for the consumption of these food products. Pyruvic acid can be found primarily in most biofluids, including sweat, blood, urine, and feces, as well as throughout most human tissues. Pyruvic acid exists in all living species, ranging from bacteria to humans. In humans, pyruvic acid is involved in several metabolic pathways, some of which include glycogenosis, type IB, glycolysis, urea cycle, and gluconeogenesis. Pyruvic acid is also involved in several metabolic disorders, some of which include non ketotic hyperglycinemia, pyruvate dehydrogenase complex deficiency, fructose-1,6-diphosphatase deficiency, and 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency. Moreover, pyruvic acid is found to be associated with anoxia, schizophrenia, fumarase deficiency, and meningitis. Pyruvic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Pyruvic acid is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalanc. Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through a reaction with acetyl-CoA. It can also be used to construct the amino acid alanine and can be converted into ethanol or lactic acid via fermentation . Those taking large doses of supplemental pyruvate—usually greater than 5 grams daily—have reported gastrointestinal symptoms, including abdominal discomfort and bloating, gas and diarrhea. One child receiving pyruvate intravenously for restrictive cardiomyopathy died (DrugBank). Pyruvate serves as a biological fuel by being converted to acetyl coenzyme A, which enters the tricarboxylic acid or Krebs cycle where it is metabolized to produce ATP aerobically. Energy can also be obtained anaerobically from pyruvate via its conversion to lactate. Pyruvate injections or perfusions increase contractile function of hearts when metabolizing glucose or fatty acids. This inotropic effect is striking in hearts stunned by ischemia/reperfusion. The inotropic effect of pyruvate requires intracoronary infusion. Among possible mechanisms for this effect are increased generation of ATP and an increase in ATP phosphorylation potential. Another is activation of pyruvate dehydrogenase, promoting its own oxidation by inhibiting pyruvate dehydrogenase kinase. Pyruvate dehydrogenase is inactivated in ischemia myocardium. Yet another is reduction of cytosolic inorganic phosphate concentration. Pyruvate, as an antioxidant, is known to scavenge such reactive oxygen species as hydrogen peroxide and lipid peroxides. Indirectly, supraphysiological levels of pyruvate may increase cellular reduced glutathione (T3DB). Pyruvic acid or pyruvate is a simple alpha-keto acid. It is a three-carbon molecule containing a carboxylic acid group and a ketone functional group. Pyruvate is the simplest alpha-keto acid and according to official nomenclature by IUPAC, it is called alpha-keto propanoic acid. Like other keto acids, pyruvic acid can tautomerize from its ketone form to its enol form, containing a double bond and an alcohol. Pyruvate is found in all living organisms ranging from bacteria to plants to humans. It is intermediate compound in the metabolism of carbohydrates, proteins, and fats. Pyruvate is a key intermediate in several metabolic pathways throughout the cell. In particular, pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through a reaction with acetyl-CoA. Pyruvic acid supplies energy to cells through the citric acid cycle (TCA or Krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactate when oxygen is lacking (lactic acid). In glycolysis, phosphoenolpyruvate (PEP) is converted to pyruvate by pyruvate kinase. This reaction is strongly exergonic and irreversible. In gluconeogenesis, it takes two enzymes, pyruvate carboxylase and PEP carboxykinase, to catalyze the reverse transformation of pyruvate to PEP. Pyruvic acid is also a metabolite of Corynebacterium (PMID: 27872963). Pyruvic acid. CAS Common Chemistry.

Butyric acid

Butyric acid magnesium salt

C4H8O2 (88.0524)


Butyric acid is a short-chain fatty acid (SCFA) formed in the mammalian colon by bacterial fermentation of carbohydrates (including dietary fibre). It is a straight-chain alkyl carboxylic acid that appears as an oily, colorless liquid with an unpleasant (rancid butter) odor. The name butyric acid comes from the Greek word for "butter", the substance in which it was first found. Triglycerides of butyric acid constitute 3‚Äì4\\% of butter. When butter goes rancid, butyric acid is liberated from the short-chain triglycerides via hydrolysis. Butyric acid is a widely distributed SCFA and is found in all organisms ranging from bacteria to plants to animals. It is present in animal fat and plant oils, bovine milk, breast milk, butter, parmesan cheese, body odor and vomit. While butyric acid has an unpleasant odor, it does have a pleasant buttery taste. As a result, butyric acid is used as a flavoring agent in food manufacturing. Low-molecular-weight esters of butyric acid, such as methyl butyrate, also have very pleasant aromas or tastes. As a result, several butyrate esters are used as food and perfume additives. Butyrate is naturally produced by fermentation processes performed by obligate anaerobic bacteria found in the mammalian gut. It is a metabolite of several bacterial genera including Anaerostipes, Coprococcus, Eubacterium, Faecalibacterium and Roseburia (PMID: 12324374; PMID: 27446020). Highly-fermentable fiber residues, such as those from resistant starch, oat bran, pectin, and guar can be transformed by colonic bacteria into butyrate. One study found that resistant starch consistently produces more butyrate than other types of dietary fibre (PMID: 14747692). The production of butyrate from fibres in ruminant animals such as cattle is responsible for the butyrate content of milk and butter. Butyrate has a number of important biological functions and binds to several specific receptors. In humans, butyric acid is one of two primary endogenous agonists of human hydroxycarboxylic acid receptor 2 (HCA2), a G protein-coupled receptor. Like other SCFAs, butyrate is also an agonist at the free fatty acid receptors FFAR2 and FFAR3, which function as nutrient sensors that facilitate the homeostatic control of energy balance. Butyrate is essential to host immune homeostasis (PMID: 25875123). Butyrates effects on the immune system are mediated through the inhibition of class I histone deacetylases (specifically, HDAC1, HDAC2, HDAC3, and HDAC8) and activation of its G-protein coupled receptor targets including HCA2, FFAR2 and FFAR3. Among the short-chain fatty acids, butyrate is the most potent promoter of intestinal regulatory T cells in vitro and the only SCFA that is an HCA2 ligand (PMID: 25741338). Butyrate has been shown to be a critical mediator of the colonic inflammatory response. It possesses both preventive and therapeutic potential to counteract inflammation-mediated ulcerative colitis and colorectal cancer. As a short-chain fatty acid, butyrate is metabolized by mitochondria as an energy source through fatty acid metabolism. In particular, it is an important energy source for cells lining the mammalian colon (colonocytes). Without butyrate, colon cells undergo autophagy (i.e., self-digestion) and die. Butyric acid, also known as butyrate or butanoic acid, is a member of the class of compounds known as straight chain fatty acids. Straight chain fatty acids are fatty acids with a straight aliphatic chain. Thus, butyric acid is considered to be a fatty acid lipid molecule. Butyric acid is soluble (in water) and a weakly acidic compound (based on its pKa). Butyric acid can be found in a number of food items such as cinnamon, pepper (c. baccatum), burdock, and mandarin orange (clementine, tangerine), which makes butyric acid a potential biomarker for the consumption of these food products. Butyric acid can be found primarily in most biofluids, including saliva, breast milk, feces, and cerebrospinal fluid (CSF), as well as throughout most human tissues. Butyric acid exists in all eukaryotes, ranging from yeast to humans. In humans, butyric acid is involved in a couple of metabolic pathways, which include butyrate metabolism and fatty acid biosynthesis. Moreover, butyric acid is found to be associated with aIDS. Butyric acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Butyric acid was first observed in impure form in 1814 by the French chemist Michel Eugène Chevreul. By 1818, he had purified it sufficiently to characterize it. However, Chevreul did not publish his early research on butyric acid; instead, he deposited his findings in manuscript form with the secretary of the Academy of Sciences in Paris, France. Henri Braconnot, a French chemist, was also researching the composition of butter and was publishing his findings, and this led to disputes about priority. As early as 1815, Chevreul claimed that he had found the substance responsible for the smell of butter. By 1817, he published some of his findings regarding the properties of butyric acid and named it. However, it was not until 1823 that he presented the properties of butyric acid in detail. The name of butyric acid comes from the Latin word for butter, butyrum (or buturum), the substance in which butyric acid was first found . If the compound has been ingested, rapid gastric lavage should be performed using 5\\% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of -oximes has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally (T3DB).

Acetoin

1-Hydroxyethyl methyl ketone

C4H8O2 (88.0524)


Acetoin, also known as dimethylketol or 2,3-butanolone, belongs to the class of organic compounds known as acyloins. These are organic compounds containing an alpha hydroxy ketone. Acyloins are formally derived from reductive coupling of carboxylic acyl groups. Thus, acetoin is considered to be an oxygenated hydrocarbon lipid molecule. Acetoin is used as an external energy store by a number of fermentive bacteria. Acetoin, along with diacetyl, is one of the compounds giving butter its characteristic flavor. Acetoin is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Acetoin is used as a food flavoring (in baked goods) and a fragrance. Acetoin is a sweet, buttery, and creamy tasting compound. Outside of the human body, Acetoin has been detected, but not quantified in several different foods, such as cocoa and cocoa products, evergreen blackberries, orange bell peppers, tortilla chips, and pomes. This could make acetoin a potential biomarker for the consumption of these foods. Constituent of beer, wine, fresh or cooked apple, fresh or cooked leak, corn, honey, cocoa, butter, cheeses, roasted coffee and other foodstuffs. Acetoin, with regard to humans, has been found to be associated with several diseases such as eosinophilic esophagitis and ulcerative colitis; acetoin has also been linked to the inborn metabolic disorder celiac disease. Acetoin is a colorless or pale yellow to green yellow liquid with a pleasant, buttery odor. It can be found in apples, butter, yogurt, asparagus, black currants, blackberry, wheat, broccoli, brussels sprouts, cantaloupe.

Ethyl acetate

Ethyl ester OF acetic acid

C4H8O2 (88.0524)


Ethyl acetate, also known as 1-acetoxyethane or acetic ester, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Ethyl acetate exists in all eukaryotes, ranging from yeast to humans. Ethyl acetate is a sweet, anise, and balsam tasting compound. Ethyl acetate is found, on average, in the highest concentration within a few different foods, such as milk (cow), pineapples, and sweet oranges and in a lower concentration in safflowers. Ethyl acetate has also been detected, but not quantified, in several different foods, such as alcoholic beverages, oxheart cabbages, agaves, chervils, ryes, and peach. It is used in artificial fruit essences. In the field of entomology, ethyl acetate is an effective asphyxiant for use in insect collecting and study. Because it is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. In a killing jar charged with ethyl acetate, the vapors will kill the collected (usually adult) insect quickly without destroying it. In organic and in natural products chemistry ethyl acetate is often used as a solvent for reactions or extractions. Ethyl acetate is a potentially toxic compound. Ethyl acetate, with regard to humans, has been found to be associated with several diseases such as perillyl alcohol administration for cancer treatment, crohns disease, nonalcoholic fatty liver disease, and pervasive developmental disorder not otherwise specified; ethyl acetate has also been linked to the inborn metabolic disorder celiac disease. Found in cereal crops, radishes, fruit juices, beer, wine, spirits etc. and produced by Anthemis nobilis (Roman chamomile) and Rubus subspecies It is used in artificial fruit essences. It is used as a solvent in the manufacture of modified hop extract and decaffeinated tea or coffeeand is also used for colour and inks used to mark fruit or vegetables

A 2-oxo monocarboxylic acid that is the 2-keto derivative of propionic acid. It is a metabolite obtained during glycolysis. Pyruvic acid is an intermediate compound in the metabolism of carbohydrates, proteins, and fats. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures (From Stedman, 26th ed.). Biological Source: Intermediate in primary metabolism including fermentation processes. Present in muscle in redox equilibrium with Lactic acid. A common constituent, as a chiral cyclic acetal linked to saccharide residues, of bacterial polysaccharides. Isolated from cane sugar fermentation broth and peppermint. Constituent of Bauhinia purpurea, Cicer arietinum (chickpea), Delonix regia, Pisum sativum (pea) and Trigonella caerulea (sweet trefoil) Use/Importance: Reagent for regeneration of carbonyl compdounds from semicarbazones, phenylhydrazones and oximes. Flavoring ingredient (Dictionary of Organic Compounds); Pyruvate is a key intersection in the network of metabolic pathways. Pyruvate can be converted into carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to the amino acid alanine and to ethanol. Therefore it unites several key metabolic processes.; Pyruvate is an important chemical compound in biochemistry. It is the output of the anaerobic metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. Pyruvate is converted into acetyl-coenzyme A, which is the main input for a series of reactions known as the Krebs cycle. Pyruvate is also converted to oxaloacetate by an anaplerotic reaction which replenishes Krebs cycle intermediates; alternatively, the oxaloacetate is used for gluconeogenesis. These reactions are named after Hans Adolf Krebs, the biochemist awarded the 1953 Nobel Prize for physiology, jointly with Fritz Lipmann, for research into metabolic processes. The cycle is also called the citric acid cycle, because citric acid is one of the intermediate compounds formed during the reactions.; Pyruvic acid (CH3COCOOH) is an organic acid. It is also a ketone, as well as being the simplest alpha-keto acid. The carboxylate (COOH) ion (anion) of pyruvic acid, CH3COCOO-, is known as pyruvate, and is a key intersection in several metabolic pathways. It can be made from glucose through glycolysis, supplies energy to living cells in the citric acid cycle, and can also be converted to carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to the amino acid alanine and to ethanol.; Pyruvic acid is a colorless liquid with a smell similar to that of acetic acid. It is miscible with water, and soluble in ethanol and diethyl ether. In the laboratory, pyruvic acid may be prepared by heating a mixture of tartaric acid and potassium hydrogen sulfate, by the oxidation of propylene glycol by a strong oxidizer (eg. potassium permanganate or bleach), or by the hydrolysis of acetyl cyanide, formed by reaction of acetyl chloride with potassium cyanide:; Pyruvic acid or pyruvate is a key intermediate in the glycolytic and pyruvate dehydrogenase pathways, which are involved in biological energy production. Pyruvate is widely found in living organisms. It is not an essential nutrient since it can be synthesized in the cells of the body. Certain fruits and vegetables are rich in pyruvate. For example, an average-size red apple contains approximately 450 milligrams. Dark beer and red wine are also rich sources of pyruvate. Recent research suggests that pyruvate in high concentrations may have a role in cardiovascular therapy, as an inotropic agent. Supplements of this dietary substance may also have bariatric and ergogenic applications. Pyruvic acid is isolated from cane sugar fermentation broth, Cicer arietinum (chickpea), Pisum sativum (pea), Trigonella cerulea (sweet trefoil) and peppermint. It can be used as a flavouring ingredient. Pyruvic acid is an intermediate metabolite in the metabolism of carbohydrates, proteins, and fats.
