Description2-Isopropyl-3-oxosuccinate belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms. 2-Isopropyl-3-oxosuccinate is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Isopropyl-3-oxosuccinate exists in all living species, ranging from bacteria to humans. 2-isopropyl-3-oxosuccinate can be biosynthesized from 3-isopropylmalate through the action of the enzymes 3-isopropylmalate dehydrogenase and D-malate / 3-isopropylmalate dehydrogenase (decarboxylating). In yeast, 2-isopropyl-3-oxosuccinate is involved in the metabolic pathway called leucine biosynthesis pathway.
