Chemical Information
FooDB Name2-Hydroxy-3-methylpentanoic acid
Description2-Hydroxy-3-methylpentanoic acid or 2-hydroxy-3-methylvaleric acid (HMVA) is an organic acid generated by L-isoleucine metabolism. It is derived from the reduction of 2-Keto-3-methylvaleric acid (KMVA), possibly through the action of a lactate dehydrogenase (PMID: 1429566). There are 4 stereoisomers of HMVA (2S,3S-HMVA, 2R,3R-HMVA, 2S,3R-HMVA and 2R,3S-HMVA), of which the 2S,3S and 2S,3R derivatives are generally separable. HMVA is found in the urine and blood of normal individuals but in very elevated levels in patients with maple syrup urine disease (MSUD) (PMID: 1429566). Maple syrup urine disease (MSUD) is an inherited metabolic disease predominantly characterized by neurological dysfunction including psychomotor/delay/mental retardation. [HMDB]
