Common Name | 3-Hydroxy-2-methyl-[S-(R,R)]-butanoic acid |
---|
Description | 3-Hydroxy-2-methyl-butanoic acid (HMBA) is a normal urinary metabolite involved in the isoleucine catabolism, as well as presumably b-oxidation of fatty acids and ketogenesis, excreted in abnormally high amounts in beta-ketothiolase deficiency. Differences in the enantiomeric ratio of HMBA may originate from the enantioselectivity of different enzyme systems (PMID 10755375 ). |
