Metabolite Identification
Common NameDiketogulonic acid
DescriptionDiketogulonic acid (DKG) is a metabolite of the degradation of vitamin C, the nonenzymatic hydrolysis-product of dehydroascorbate. Dehydroascorbate can be reduced back to ascorbate or hydrolyzed to DKG; the latter reaction is irreversible and DKG is devoid of antiscorbutic activity. The degradation pathway of vitamin C continues to produce l-erythrulose and oxalate as final products. DKG appears in human urine and represents approximately 20% of the vitamin C by-products (oxalate being approximately 44% and dehydroascorbate 20%). A major catabolic event in man is the cleavage of the molecule (presumably a spontaneous cleavage of DKG) between C2 and C3, with little if any decarboxylation. The oxalate formed in this way may contribute to the formation of kidney stones in susceptible individuals. However, the association between ascorbate supplementation and increased risk of kidney stone formation remains a matter of controversy. (PMID: 16698813 , 17222174 )
