Keto acid

In organic chemistry, keto acids or ketoacids (also called oxo carboxylic acids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). In several cases, the keto group hydrates to the corresponding acetal in aqueous solution. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in glycolysis.
