acetaldehydeThe major metabolic product of ethanol, which is generated by ethanol dehydrogenase and subsequently metabolised to acetate by aldehyde dehydrogenase. It is responsible for alcohol’s toxic effects.
It is postulated that the liver injury induced by ethanol is due to tissue responses to acetaldehyde, including acetaldehyde-induced fibrogenesis, acetaldehyde-induced lipid peroxidation enzyme inhibition, and formation of antibodies against acetaldehyde adduct proteins—e.g., serum albumin, hemoglobin, and cytokskeletal proteins, including tubulin.

An intermediary product in the metabolism of alcohol.

acetaldehydeA product of the metabolism of large amounts of alcohol. The reaction is catalyzed in the liver by the enzyme alcohol dehydrogenase. The principal cause of the toxic effects of strong drink. Acetaldehyde is a powerful poison, considerably more toxic than alcohol, and is capable of damaging almost any part of the body. Fortunately the body has a range of detoxifying enzymes, aldehyde dehydrogenases, one of which, ALDH2, rapidly break down the acetaldehyde molecule.
