Metabolite Identification
Common NameAscorbic acid 2-sulfate
DescriptionAscorbic acid 2-sulfate (AAS) or Vitamin C sulfate belongs to the class of organic compounds known as butenolides. These are dihydrofurans with a carbonyl group at the C2 carbon atom. Ascorbic acid 2-sulfate is an extremely weak basic (essentially neutral) compound (based on its pKa). Ascorbic acid 2-sulfate is a metabolite of vitamin C. In humans, vitamin C is typically metabolized into dehydroascorbic acid, diketogulonic acid, oxalate, ascorbate-2-sulfate, and methyl ascorbate. Ascorbate-2-sulfate is a Phase II metabolite of ascorbate (vitamin C) arising from the action of a liver-derived sulfotransferase on vitamin C.  Vitamin C, also known as L-ascorbic acid or L-ascorbate, is an essential nutrient for humans and certain other animal species. In living organisms, ascorbate acts as an antioxidant by protecting the body against oxidative stress. It is also a cofactor in at least eight enzymatic reactions including several collagen synthesis reactions that, when dysfunctional, cause the most severe symptoms of scurvy (Wikipedia).
