WebNational Center for Biotechnology Information WebAlcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH, OH) into nontoxic substances. Methyl alcohol acts as a competitive inhibitor of ethyl alcohol by competing for the same active site on ADH. When attached to ADH, methyl alcohol is converted to formaldehyde, which is toxic in the body.
