Origin of pyruvic acid:
1830–40; pyr - + L ūv(a) grape + -ic
a colorless acid formed as an important intermediate in metabolism or fermentation
a colourless liquid; an important intermediate in the metabolism of proteins and carbohydrates, and in fermentation
the simplest aliphatic keto acid, CHCOCOOH
Pyruvic acid is an organic acid, a ketone, as well as the simplest of the alpha-keto acids. The carboxylate anion of pyruvic acid, its Brønsted–Lowry conjugate base, CH3COCOO−, is known as pyruvate, and is a key intersection in several metabolic pathways. Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates via gluconeogenesis, or to fatty acids through acetyl-CoA. It can also be used to construct the amino acid alanine and be converted into ethanol. Pyruvic acid supplies energy to living cells through the citric acid cycle when oxygen is present, and alternatively ferments to produce lactic acid when oxygen is lacking.
U.S. National Library of Medicine
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)
