WebThe cytoplasm of liver cells contain an enzyme called alcohol dehydrogenase (ADH) that catalyzes the oxidation of ethanol to acetaldehyde (Figure 1.11). The oxidation occurs when ethanol binds to a site on the ADH enzyme and loses some electrons in the form of H atoms. Actually ethanol gives up 2 H atoms to another molecule that also binds to ADH. WebADH is the major enzyme responsible for conversion of ethanol to acetaldehyde. The rate (kinetics) of conversion is dependent on the allelic form of the dimeric enzyme ( …
