Oxidation of Ethanol to Acetaldehyde

C2H5OH + [O] → CH3CHO + H2O

개요

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.
