General description

Natural occurrence: Asparagus, beef, sake, Virginia tobacco, wheat bread.
Pyruvic acid is the key component formed during the hydrolysis of flavor-precursors called S-alk(en)yl-L-cysteine-sulfoxides in onion tissues by allinase during maceration or chopping. The amount of pyruvic acid formed is used as a measure for onion pungency.

Lactate is an important intermediate metabolite in human bioenergetics and is oxidized in many different tissues including the heart, brain, kidney, adipose tissue, liver, and skeletal muscle. The mechanism(s) explaining the metabolism of lactate in these tissues, however, remains unclear.
