Metabolite Identification
Common NameDehydroascorbic acid
DescriptionDehydroascorbic acid is the oxidized form of vitamin C. Reduced Vitamin C concentrations in the brain exceed those in blood by 10 fold. Dehydroascorbic acid readily enters the brain and is retained in the brain tissue in the form of ascorbic acid (ascorbic acid is not able to cross the blood-brain barrier). Therefore, transport of dehydroascorbic acid by the Glucose Transporter 1 (GLUT1, Glucose transporters are integral membrane glycoproteins involved in transporting glucose into most cells. GLUT1 is a major glucose transporter in the mammalian blood-brain barrier. It is present at high levels in primate erythrocytes and brain endothelial cells.) is a mechanism by which the brain acquires vitamin C. (OMIM 138140 ).

General function:
Involved in monooxygenase activity
Specific function:
Bifunctional enzyme that catalyzes 2 sequential steps in C-terminal alpha-amidation of peptides. The monooxygenase part produces an unstable peptidyl(2-hydroxyglycine) intermediate that is dismutated to glyoxylate and the corresponding desglycine peptide amide by the lyase part. C-terminal amidation of peptides such as neuropeptides is essential for full biological activity.
