Alcohol dehydrogenase class-3 is an enzyme that in humans is encoded by the ADH5 gene.^[5]^[6]^[7]

This gene encodes glutathione-dependent formaldehyde dehydrogenase or the class III alcohol dehydrogenase chi subunit, which is a member of the alcohol dehydrogenase family. Members of this family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. Class III alcohol dehydrogenase is a homodimer composed of 2 chi subunits. It has virtually no activity for ethanol oxidation, but exhibits high activity for oxidation of long-chain primary alcohols and for oxidation of S-hydroxymethyl-glutathione, a spontaneous adduct between formaldehyde and glutathione.

This enzyme is an important component of cellular metabolism for the elimination of formaldehyde, a potent irritant and sensitizing agent that causes lacrymation, rhinitis, pharyngitis, and contact dermatitis.^[7]

Clinical significance[edit]

Mutations of the ADH5 gene cause AMED syndrome, an autosomal recessive digenic multisystem disorder characterized by global developmental delay with impaired intellectual development. The syndrome was first described in 2020.
