Metabolite Identification
Common NameAscorbic acid-2-sulfate
DescriptionAscorbic acid-2-sulfate is a metabolite of vitamin c. Vitamin C or 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)
