| Pyruvic acid Usage And Synthesis |
| Uses | Intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, Pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. The liver can convert Pyruvic acid to alanine by amination. A diagnostic agent for Parkinson disease. |
| Antioxidant effect | Studies have shown that pyruvic acid can inhibit the oxidation of oxygen free radicals in mice, and as a hydrogen peroxide scavenger, it has the effect of preventing free radical damage, and it has been proved to be protective in cardiac reperfusion injury and acute renal failure. The body resists functional damage. Pyruvic acid can act as an antioxidant through two mechanisms: first, as an α-keto acid, pyruvic acid can directly inhibit hydrogen peroxide through a non-enzymatic decarbonation reaction; second, supplementation of pyruvic acid can enhance In the citric acid cycle, after the production of citric acid increases, the phosphofructokinase is inhibited, thereby entering the pentose phosphate bypass to generate reduced coenzyme II (NADPH), thereby indirectly increasing the ability of the glutathione (GSH) antioxidant system. Pyruvic acid can also increase the ratio of coenzyme I/reduced coenzyme I (NAD+/NADH) and promote the reaction of the tricarboxylic acid cycle. |
| Chemical Properties | Colorless to light yellow liquid |
| Chemical Properties | Pyruvic acid has a sour, acetic odor (similar to acetic acid). It has a pleasant, sour taste with a burning, somewhat sweet note. It tends to darken and decompose unless kept free of minor contaminants and in tightly sealed containers |
| Occurrence | Isolated from cane sugar fermentation broth and from a few plants; also reported found in peppermint, raw asparagus, leaves and stalk of celery, onion, rutabaga, milk, cream, buttermilk, wheaten bread, blue cheeses, cheddar cheese, cottage cheese, provolone cheese, yogurt, beef, Virginia tobacco, beer, white wine, botrytised wine, cocoa and sake. |
| Uses | Pyruvic acid is used as a component in culture broths and media as commercial red seaweed polysaccharide. It is involved in the construction of amino acid alanine as well as supplies energy to living cells via citric acid cycle (Krebs cycle). It reacts with N-acetyl mannosamine by an aldol-type condensation to prepare sialic acid. It is employed to study the cultivation of soil bacteria as micro colonies using soil substrate membrane system. It finds application in liquid chromatography and in the determination of organic acids in red wine. |
| Uses | pyruvic 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. |
| Uses | Biochemical research. |
| Definition | A fundamen- tal intermediate in protein and carbohydrate metabolism in the cell. |
| Preparation | 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. |
| Aroma threshold values | Aroma characteristics at 1.0%: acidic, sweet, caramellic and sour. |
