Mammalian Liver Alcohol Dehydrogenases

Abstract
In mammals, ethanol metabolism takes place mainly in the liver where it is first converted to acetaldehyde and further to acetic acid (1,2,3). In experimental animals and in humans (4), liver alcohol dehydrogenase (ADH) is responsible for the metabolism of at least 80% of administered ethanol, at concentrations below 0.2% the contribution of any other ethanol metabolizing systems being relatively small (5).
