pyruvic acid



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.

The researchers decided to examine whether genetically diminishing the entry of pyruvate into the mitochondria would force hair follicle stem cells to make more lactate, and if that would activate the cells and grow hair more quickly.
We also found that pika LDH-C4 has an affinity for pyruvate that is 90-fold higher than that for lactate in our prevoious study, and it was beneficial to catalyze the conversion of pyruvate to lactate even at high concentration of lactate in our previous study (Wang et al., 2016).

Lactate can be metabolized by various cells and tissues, for example, liver, germ cells, and neurons, converting to pyruvate via LDH and subsequently to glycogen or carbon dioxide [22].
