Claim: ADH1B is not involved in encoding a protein in the alcohol dehydrogenase family, a group of enzymes that occur in many organisms.
Evidence: Alcohol dehydrogenase 1B is an enzyme that in humans is encoded by the ADH1B gene. Alcohol dehydrogenases (ADH) (EC ) 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.
