독성 정보
Toxicity Summary
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.

Pharmacodynamics
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.

용도pyruvic acid is an alpha hydroxy acid that can be irritating and is considered difficult to work with. It has a larger molecular size than the most commonly used AHAs. Sodium pyruvate is more commonly used, and is an organic salt.
일반 설명Pyruvic acid is the key component formed during the hydrolysis of flavor-precursors called S-alk(en)yl-L-cysteine-sulfoxides in onion tissues by allinase during maceration or chopping. The amount of pyruvic acid formed is used as a measure for onion pungency.
제조 방법
By distillation of tartaric acid in the presence of potassium acid sulfate as a dehydrating agent; from acetyl chloride and potassium cyanide to yield the nitrile, which is subsequently acid hydrolyzed to the acid; pyruvic acid must be rectified under vacuum.

추가 설명
정의Pyruvic acid is an important organic chemical intermediate, an intermediate compound in the metabolism of carbohydrates, proteins, and fats, and is used in a variety of fields, including the pharmaceutical, cosmetic, food, and chemical industries. It has roles as a basic metabolite and cofactor. In thiamine deficiency, its oxidation is retarded and it tends to accumulate in neurostructural tissues causing neurological damage. In vitro studies have shown that pyruvic acid modulates cardiac function at physiological or low doses, but can cause cardiomyocyte damage at high doses.
