Identification
Name:	2-Keto-3-methyl-valerate
Description	3-Methyl-2-oxovaleric acid is a metabolite of isoleucine in man, animals and bacteria. It is the alpha-keto acid analogue of isoleucine. 3-Methyl-2-oxovaleric acid is produced from isoleucine by cytosolic branched chain aminotransferase 1 (EC:2.6.1.42), whereupon it is further degraded by branched chain keto acid dehydrogenase E1 to 2-Methyl-1-hydroxybutyl-ThPP.
