alcohol dehydrogenase. (biochemistry). The enzyme that catalyzes the oxidation of ethanol to acetaldehyde.
A small amount of alcohol is not metabolized and is excreted through sweat, saliva, urine, and the breath. In the liver an enzyme known as alcohol dehydrogenase (ADH) converts alcohol to acetaldehyde. This substance is then converted to acetic acid and then metabolizes to carbon dioxide, water, and fatty acids.
