Metabolite Identification
Common NameGalactonolactone
DescriptionGalactonolactone has been determined in human urine by reversed-phase HPLC for the specific evaluation of metabolic by-products in the urine of galactosemic patients and based on the simultaneous determination of gluconolactone, galactonolactone and galactitol. (PMID: 1797843 ). Patients with galactose-1-phosphate uridyltransferase (GALT) deficiency, given a load of galactose have been shown to excrete six times as much galactonate in their urine as normal subjects exposed to the same experimental conditions. The production of galactonate occurs through the activity of a soluble NAD+-dependent galactose dehydrogenase, catalyzing the conversion of galactose to D-galactonolactone (D-galactose: NAD+ oxidoreductase, EC 1.1.1.48). (OMMBID).

Chemical Taxonomy
Description Belongs to the class of organic compounds known as lactones. These are cyclic esters of hydroxy carboxylic acids, containing a 1-oxacycloalkan-2-one structure, or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring.
