Metabolite Identification
Common NameD-Galactonate
DescriptionD-galactonate is a member of the chemical class known as Sugar Acids and Derivatives. These are compounds containing a saccharide unit which bears a carboxylic acid group. The gluconic acid is produced by direct extracellular oxidation of glucose by a glucose dehydrogenase equipped with pyrroloquinoline quinone (PQQ) as a cofactor. (PMID 14756528 ) Glucuronate is converted to l-gulonate by aldehyde reductase, an enzyme of the aldo-keto reductase superfamily. l-Gulonate is converted to l-gulonolactone by a lactonase identified as SMP30 or regucalcin, whose absence in mice leads to vitamin C deficiency.
