Pyruvic acid , also called acetylformic acid , is the simplest of the keto carboxylic acids . Their salts and esters are called pyruvates . In biochemistry , pyruvate is the anion of pyruvic acid and is a C-3 body. The pyruvic acid molecule has an α- carbonyl group . The acyl residue (CH 3 COCO–) of pyruvic acid is called pyruvoyl .
The name pyruvic acid is derived from the first production: tartaric acid was subjected to dry distillation (what was then known as pyruvic acid ); this creates pyruvic acid after decarboxylation and splitting off of water. In English the compound is called pyruvic acid , derived from the Greek pyr (fire, heat) and the Latin uva (grape, especially grape).
Jöns Jakob Berzelius represented pyruvic acid around 1835 by jointing tartaric acid with potassium hydrogen sulfate.
The flash point of the colorless liquid, which can be mixed with any water, is 82 ° C.
