'''α-Acetolactic acid''' 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.<ref>{{cite book | chapter-url = https://books.google.com/books?id=Q8B_WusVacsC&pg=PA185 | chapter = Carbohydrate Metabolism | isbn = 978-0-7514-0215-5 | volume =2 | title = The Lactic Acid Bacteria: The genera of lactic acid bacteria | publisher = Springer | year = 1995 | first1 = B.
