Expert Answer:

Pyruvic acid (CH3COCOOH) is an organic acid, a ketone, as well as the simplest of alpha-keto acids. The carboxylate (COO?) anion of pyruvic acid is known as pyruvate.

Pyruvic acid supplies energy to living cells through the Krebs cycle, when oxygen is present (aerobic respiration), and alternatively ferments to produce lactic acid when oxygen is absent (fermentation).

Lactic acid is a carboxylic acid with the chemical formula C3H6O3. It has a hydroxyl group adjacent to the carboxyl group, making it an alpha hydroxy acid (AHA).
