The alcohol dehydrogenase (ADH) family of enzymes catalyzes the reversible oxidation of alcohol to acetaldehyde. Seven ADH genes exist in a segment of 370 kb on 4q21.
Products of the three class I ADH genes that share 95% sequence identity are believed to play the major role in the first step of ethanol metabolism.
