AI overview
Acetaldehyde is a common organic chemical that exists as a colorless liquid or gas and occurs naturally in foods like coffee, bread, and ripe fruit, while also being produced in large quantities by industry. It's notable because your liver produces it when breaking down alcohol—a process that contributes to hangovers—and because it's one of the most important aldehydes found throughout nature and the environment.

Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula . It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry. Acetaldehyde occurs naturally in coffee, bread, and ripe fruit, and is produced by plants. It is also produced by the partial oxidation of ethanol by the liver enzyme alcohol dehydrogenase and is a contributing cause of hangover after alcohol consumption. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke. Consumption of disulfiram inhibits acetaldehyde dehydrogenase, the enzyme responsible for the metabolism of acetaldehyde, thereby causing it to build up in the body.
The International Agency for Research on Cancer (IARC) has listed acetaldehyde as a Group 1 carcinogen. Acetaldehyde is "one of the most frequently found air toxins with cancer risk greater than one in a million".
