Keto acids, also known as ketoacids or oxoacids, are organic compounds that contain a carboxylic group and a ketone group. Basically, the keto acids can be classified into alpha (like pyruvic acid), beta (like acetoacetic acid), and gamma (like levulinic acid). Alpha-keto acids (α-keto acids) have a carbonyl group at the alpha site related to the carboxylic group, which are involved in the tricarboxylic acid cycle and glycolysis. The general formula of alpha-keto acids is RCOCOOH, in which R is aryl, alkenyl, or heterocyclic group.

Alpha-keto acids are important intermediate compounds to produce amino acids and regulating protein turnover in the metabolism. They have many significations, including food, animal feed, pharmaceutical, and chemical industries. In addition, alpha-keto acids can be used as biosynthetic precursors for protein. The labeled alpha-keto acids are valuable for the NMR studies of progressively larger proteins and supramolecular systems.

As a supplier of isotope labeled products in the industry, Creative Proteomics offers more than 10,000 products labeled with different isotopes of carbon, hydrogen, nitrogen, and oxygen.
