What's Ascorbic Acid
Vitamin C, also known as L-ascorbic acid, is an essential nutrient for higher primates and a few other organisms. Ascorbic acid is metabolically produced in most organisms, but humans are the most notable exception. The most well-known is that lack of Chemicalbook vitamin C can cause scurvy. The pharmacophore of vitamin C is the ascorbate ion. In living organisms, vitamin C is an antioxidant because it protects the body from oxidant threats, and it is also a coenzyme.
