Ascorbic acid 2-sulfate

[(5R)-5-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-2-oxo-2,5-dihydrofuran-3-yl]oxidanesulfonic acid

C6H8O9S (255.9889)


Ascorbic acid 2-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. 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).
