methylmalonic acid has been researched along with Nervous System Disorders in 21 studies
Methylmalonic Acid: A malonic acid derivative which is a vital intermediate in the metabolism of fat and protein. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This metabolic disease is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA.
methylmalonic acid : A dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group.
