pyruvic

Pyruvic acid (Acetylformic 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.

Pyruvic aldehyde (2-Oxopropanal) is a highly reactive dicarbonyl compound that can be converted to lactic acid by evolution from DHA and GLA.

Indole-3-pyruvic acid (3-(3-Indolyl)-2-oxopropanoic acid) is a compound involved in the biosynthesis of Indole-3-acetic acid, a plant hormone which plays important roles in regulating growth and responses to environmental changes.

Potassium 1-carboxyvinyl hydrogenphosphate (PEP-K) is involved in glycolysis and gluconeogeneis. In glycolysis, PEP is metabolized by Pyruvate Kinase to yield pyruvate. In plants, PEP is involved in the formation of aromatic amino acids as well as in the carbon fixation pathway.

Ethyl pyruvate is a simple aliphatic ester of pyruvic acid and has been shown to have robust neuroprotective effects via its anti-inflammatory, anti-oxidative, and anti-apoptotic functions.

Hydroxypyruvic acid is an intermediate in the metabolism of glycine, serine, and threonine. It is a substrate for serine-pyruvate aminotransferase and glyoxylate reductase/hydroxypyruvate reductase.

4-Hydroxyphenylpyruvic acid is an enzyme inhibitor.4-Hydroxyphenylpyruvic acid (4-HPPA) is a keto acid that is involved in the tyrosine catabolism pathway. It is a product of the enzyme (R)-4-hydroxyphenyllactate dehydrogenase (EC 1.1.1.222) and is formed during tyrosine metabolism. The conversion from tyrosine to 4-HPPA is catalyzed by tyrosine aminotransferase. Additionally, 4-HPPA can be converted to homogentisic acid which is one of the precursors to ochronotic pigment. The enzyme 4-hydroxyphenylpyruvic acid dioxygenase (HPD) catalyzes the reaction that converts 4-hydroxyphenylpyruvic acid to homogentisic acid. A deficiency in the catalytic activity of HPD is known to lead to tyrosinemia type III, an autosomal recessive disorder characterized by elevated levels of blood tyrosine and massive excretion of tyrosine derivatives into urine. It has been shown that hawkinsinuria, an autosomal dominant disorder characterized by the excretion of 'hawkinsin,' may also be a result of HPD deficiency . Moreover, 4-hydroxyphenylpyruvic acid is also found to be associated in phenylketonuria, which is also an inborn error of metabolism. There are two isomers of HPPA, specifically 4HPPA and 3HPPA, of which 4HPPA is the most common.

Phenylpyruvic acid (3-Phenylpyruvic acid) is a keto-acid that is an intermediate or catabolic byproduct of phenylalanine metabolism. It has a slight honey-like odor. Levels of phenylpyruvate are normally very low in blood or urine. High levels of phenylpyruvic acid can be found in the urine of individuals with phenylketonuria (PKU), an inborn error of metabolism.

Vanilpyruvic acid is a metabolite of catecholamine and precursor of vanillactic acid.

Schisantherin A, B, C, and D show good effect in lowering the serum glutamic-pyruvic transaminase level of the patients suffering from chronic virus hepatitis.

DL-Valine (H-DL-Val-OH) is 2-amino-3-methylbutanoic acid.It is synthesized in plants via several steps starting from pyruvic acid.

1. Schisantherin B (Schizantherin-B) shows good effect in lowering the serum glutamic-pyruvic transaminase level of the patients suffering from chronic virus hepatitis.

L-Lactic acid ((S)-2-Hydroxypropanoic acid) is a natural product produced by the anaerobic glycolysis of pyruvic acid. L-Lactic acid is a sensitive indicator of tissue hypoxia and can be used as a hemodynamic indicator in critically ill patients.

A branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway.
