Oxidation of Ethanol to Acetaldehyde
C2H5OH + [O] → CH3CHO + H2O
概要
Ethanol is oxidized to acetaldehyde, with the carbon bearing the OH group changing oxidation state from -1 to +1. In the body, this reaction is catalyzed by alcohol dehydrogenase in the liver. Acetaldehyde is toxic and is responsible for many hangover symptoms.
参加者
日常の例
When you drink alcohol, your liver enzymes perform this oxidation to break down ethanol. Acetaldehyde buildup causes hangover symptoms like headache and nausea.
