Metabolites and Adducts	Source
Acetaldehyde	Ethanol metabolism
Malondialdehyde (MDA)	Nonenzymatic lipid peroxidation of unsaturated fatty acids, breakdown of arachidonic acid in platelets
4-hydroxynonenal (HNE)	Lipid peroxidation of long-chain polyunsaturated fatty acids
Malondialdehyde-Acetaldehyde Adduct (MAA)	Hybrid adducts with malondialdehyde and acetaldehyde
Hydroxyethyl radical (HER)	Ethanol oxidation in the presence of iron
