Alcohol dehydrogenase (PDB id [[1htb]]), ADH, is an enzyme that catalyzes the 4th step in the metabolism of fructose before glycolysis. In the 4th step, glyceraldehyde is converted to the glycolytic intermediate DHAP by the NADH-dependent, ADH catalyzed reduction to glycerol.<ref>Voet, et. al. ''Fundamentals of Biochemistry: 3rd Edition''. Hoboken: Wiley & Sons, Inc, 2008.</ref> ADH catalyzes the oxidation of primary and secondary alcohols to their corresponding aldehydes and ketones through a mechanism that involves the removal of a hydrogen. The alcohol dehydrogenase reaction is a bisubstrate reaction, where ADH catalyzed the transfer of a hydride ion from ethanol to NAD+. In metabolic reactions within the human liver, glyceraldehyde is reduced to glycerol through a mechanism in which NADH is reduced to NAD+, and this whole process is catalyzed by alcohol dehydrogenase.
