Acetaldehyde dehydrogenase

Acetaldehyde dehydrogenase (EC 1.2.1.10) is a dehydrogenase enzyme that converts acetaldehyde into acetic acid.

EC numbers (Enzyme Commission numbers) are a numerical classification scheme for enzymes, based on the chemical reactions they catalyze. ... A dehydrogenase is an enzyme that oxidizes a substrate by transferring one or more protons and a pair of electrons to an acceptor, usually NAD/NADP or a flavin coenzyme such as FAD or FMN. Common examples of dehydrogenase enzymes in the TCA cycle are pyruvate dehydrogenase, isocitrate dehydrogenase, and... Ribbon diagram of the catalytically perfect enzyme TIM.

The oxidation of acetaldehyde to acetate can be summarized as follows:

CH₃CHO + NAD⁺ CoA → + acetyl-CoA + NADH + H⁺

In the liver, the enzyme alcohol dehydrogenase oxidizes ethanol into acetaldehyde, which is then further converted into the harmless acetic acid by acetaldehyde dehydrogenase. Acetaldehyde is more toxic than alcohol and is responsible for many hangover symptoms. N-acetylcysteine (NAC) is known to assist in processing acetaldehyde in the body and therefore can help to relieve hangover symptoms. Acetyl-CoA (CoA with acetate highlighted) Coenzyme A (CoA, CoASH, or HSCoA) is adapted from β-mercaptoethylamine, panthothenate and adenosine triphosphate and used in metabolism in areas such as fatty acid oxidization and the citric acid cycle. ...

Some persons from far-Eastern descent have a mutation in their acetaldehyde dehydrogenase gene, making this enzyme less effective. In these people, acetaldehyde accumulates after drinking, leading to symptoms of acetaldehyde poisoning, including the characteristic flushing of the skin and increased heart and respiration rates. Individuals with deficient acetaldehyde dehydrogenase activity are far less likely to become alcoholics, but seem to be at a greater risk of liver damage, alcohol-induced asthma, and contracting cancers of the oro-pharynx and oesophagus due to acetaldehyde overexposure. Far East is an inexact term often used for East Asia and Southeast Asia combined, sometimes including also the easternmost territories of Russia, i. ...

The drug disulfiram (Antabuse®) also prevents the oxidation of acetaldehyde to acetic acid, with the same unpleasant effects for drinkers. It is used in the treatment of alcoholism. Disulfiram is a drug used to support the treatment of chronic alcoholism by producing an acute sensitivity to alcohol. ...
