pyruvic acid

 [pi-roo´vik]
a compound formed in the body in aerobic metabolism of carbohydrate; also formed by dry distillation of tartaric acid.

py·ru·vic ac·id

(pī-rū'vik as'id),
2-Oxopropanoic acid; α-ketopropionic acid; acetylformic acid; pyroacemic acid; the simplest α-keto acid; an intermediate compound in the metabolism of carbohydrate; in thiamin deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. The enol form, enol pyruvic acid, when phosphorylated, plays an important metabolic role. See: phosphoenolpyruvic acid.

pyruvic acid

/py·ru·vic ac·id/ (pi-roo´vik) CH3COCOOH, an intermediate in carbohydrate, lipid, and protein metabolism.

pyruvic acid

(pī-ro͞o′vĭk, pĭ-)
n.
A colorless organic liquid, C3H4O3, formed as an intermediate in carbohydrate metabolism and fermentation and as an end product in glycolysis.

pyruvic acid

[pīro̅o̅′vik]
a compound formed as an end product of glycolysis, the anaerobic stage of glucose metabolism. It may enter the citric acid cycle if oxygen is present. Under anaerobic conditions it may be converted to lactic acid, which accumulates in muscle tissue.

py·ru·vic ac·id

(pī-rū'vik as'id)
An intermediate compound in the metabolism of carbohydrate; in thiamin deficiency, its oxidation is retarded and it accumulates in the tissues.

pyruvic acid

or

pyruvate

an important 3-carbon molecule formed from GLUCOSE and GLYCEROL in glycolysis (see Fig. 264 ). See also ACETYLCOENZYME A. Pyruvic acid is broken down further, the precise reactions depending upon whether oxygen is present or not. See AEROBIC RESPIRATION, ANAEROBIC RESPIRATION.

pyruvic acid

a compound formed in the body in metabolism of carbohydrate; also formed by dry distillation of tartaric acid. Used synonymously with pyruvate.
