Common Name2-Methyl-3-ketovaleric acid
Description2-Methyl-3-ketovaleric acid is a metabolite of beta-leucine in the beta-keto pathway of leucine metabolism. 2-Methyl-3-ketovaleric acid is a known pathological metabolite and associated with propionic acidemia, especially during periods of ketoacidosis; a severe deficiency of propionyl-CoA carboxylase in cultured fibroblasts has been detected in some neonatal cases. (PMID 7389125 , 6820422 , 7119896 , 7430116 , 3356699 ). 2-Methyl-3-ketovaleric acid induces a strong activity of inosine-5'-monophosphate dehydrogenase (IMPDH; the rate-limiting enzyme in GTP synthesis), mimicking glucose. (PMID: 11145582 ).
