Alcohol dehydrogenase (ADH) is an enzyme that catalyzes the oxidation of primary and secondary alcohols to their corresponding aldehydes and ketones through a mechanism that involves the removal of hydrogen. | Alcohol dehydrogenase (ADH) is an enzyme that catalyzes the oxidation of primary and secondary alcohols to their corresponding aldehydes and ketones through a mechanism that involves the removal of hydrogen. In the oxidation mechanism, ADH is momentarily associated with nicontinamide adenine dinucleotide (NAD+), which functions as a cosubstrate. The reaction is shown below: CH3CH2OH + NAD+ -> CH3COH (acetaldehyde) + NADH + H+ (Note: The reaction is actually reversible although the arrow does not show it) ('''citation needed''')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. | ||
