The function of Ensembl gene identifier ENSG00000108602 (ALDH3A1, aldehyde dehydrogenase 3 family member A1) is as follows. ALDHs play a major role in the detoxification of alcohol- derived acetaldehyde (Probable). They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation (Probable). Oxidizes medium and long chain aldehydes into non-toxic fatty acids (PubMed:1737758). Preferentially oxidizes aromatic aldehyde substrates (PubMed:1737758). Comprises about 50 percent of corneal epithelial soluble proteins (By similarity). May play a role in preventing corneal damage caused by ultraviolet light (By similarity). {ECO:0000250|UniProtKB:P47739, ECO:0000269|PubMed:1737758, ECO:0000305}.
