Identification
Name: (S)-2-Acetolactate
Description:(S)-2-Acetolactate is an intermediate in the biosynthesis of valine, leucine and isoleucine (KEGG ID C06010 ). It is the sixth to last step in the synthesis of protein and is converted from 2-hydroxy-3-methyl-2-oxobutanoate via the enzyme acetolactate synthase [EC:2.2.1.6]. It is then converted to 3-hydroxy-3-methyl-2-oxobutanoate via the enzyme ketol-acid reductoisomerase [EC:1.1.1.86].
