An oxidoreductase that reversibly converts an alcohol to an aldehyde (or ketone) with NAD+ as the H acceptor. For example, ethanol + NAD+ ⇄ acetaldehyde + NADH. SEE ALSO: a. (acceptor), a. (NADP+).
An oxidoreductase that reversibly converts primary alcohols to aldehydes with an H acceptor other than NADP+.
An oxidoreductase reversibly converting alcohols to aldehydes (or ketones) with NAD(P)+ as H acceptor. SYN: aldehyde reductase.

al·co·hol de·hy·dro·gen·ase (alґkə-hol de-hiґdro-jən-ās) [EC 1.1.1.1] an enzyme of the oxidoreductase class that catalyzes the reversible oxidation of primary or secondary alcohols to aldehydes using NAD+ as an electron acceptor. The reaction is the first step in the metabolism of alcohols by the liver. Abbreviated AD and ADH.Medical dictionary. 2011.
