where is alcohol dehydrogenase found in the body
Alcohol dehydrogenase In humans, ADH exists in multiple forms as a dimer and is encoded by at least seven different genes. There are five classes (I-V) of alcohol dehydrogenase, but the hepatic form that is used primarily in humans is class 1. Class 1 consists of α, β, and γ subunits that are encoded by the genes ADH1A, ADH1B, and ADH1C.[18] The enzyme is present at high levels in the liver and the lining of the stomach.[19] It catalyzes the oxidation of ethanol to acetaldehyde (ethanal):
