Alcohol dehydrogenases (ADH) (EC 1.1.1.1) are a group of dehydrogenase enzymes that occur in many organisms and facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD+ to NADH). In humans and many other animals they serve to break down alcohols that otherwise are toxic and they also participate in generation of useful aldehyde ketone or alcohol groups during biosynthesis of various metabolites.
