Identification
Name:(S)-Methylmalonic acid semialdehyde
DescriptionMethylmalonic semialdehyde is a metabolite in valine catabolism, inositol metabolism and propanoate metabolism. Methylmalonate-semialdehyde dehydrogenase (MMSDH) catalyses the NAD+ and coenzyme A-dependent conversion of methylmalonate semialdehyde to propionyl-CoA in the distal region of the L-valine catabolic pathway. Direct enzymatic assay of MMSDH is difficult since the substrate, methylmalonate semialdehyde, is both commercially unavailable and notoriously unstable as a b-keto acid. (PMID: 10947204)
