Identification
Name: 3-Hydroxy-3-methyl-2-oxobutanoic acid
Description:3-hydroxy-3-methyl-2-oxobutanoic acid belongs to the class of Branched Fatty Acids. These are fatty acids containing a branched chain. (inferred from compound structure)α-Acetolactic acid (α-acetolactate) is a precursor in the biosynthesis of the branched chain amino acids valine and leucine. α-Acetolactic acid is produced from two molecules of pyruvic acid by acetolactate synthase. α-Acetolactic acid can also be decarboxylated by alpha-acetolactate decarboxylase to produce acetoin.
