<unk> s () are a group of enzymes that catalyse the oxidation of<unk> ydes. They convert<unk> ydes (R–C(=O)) to carboxylic acids (R–C(=O)). The oxygen comes from a water molecule. To date, nineteen<unk>  genes have been identified within the human genome. These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated<unk> ydes.

Transaminase
Aldehyde oxidase
