Common Name3-Mercaptopyruvic acid
Description3-Mercaptopyruvic acid, also known as 3-mercapto-2-oxopropanoate or beta-thiopyruvate, belongs to the class of organic compounds known as alpha-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. 3-Mercaptopyruvic acid is an intermediate in cysteine metabolism. 3-Mercaptopyruvic acid exists in all living organisms, ranging from bacteria to humans. Within humans, 3-mercaptopyruvic acid participates in a number of enzymatic reactions. In particular, 3-mercaptopyruvic acid and cyanide can be converted into pyruvic acid and thiocyanate; which is mediated by the enzyme 3-mercaptopyruvate sulfurtransferase. In addition, 3-mercaptopyruvic acid can be biosynthesized from 3-mercaptolactic acid; which is mediated by the enzyme L-lactate dehydrogenase. It has been studied as a potential treatment for cyanide poisoning, but its half-life is too short for it to be clinically effective. In humans, 3-mercaptopyruvic acid is involved in cystinosis, ocular nonnephropathic. Outside of the human body, 3-mercaptopyruvic acid has been detected, but not quantified in several different foods, such as lima beans, spinachs, shallots, mexican groundcherries, and white lupines. This could make 3-mercaptopyruvic acid a potential biomarker for the consumption of these foods.
