Ascorbic Acid with CAS 50-81-7
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 the lack of lack of vitamin C can cause scurvy.The pharmacophore of vitamin C is the ascorbic acid ion. In living organisms, vitamin C is an antioxidant because it protects the body from the threat of oxidants, and vitamin C is also a coenzyme.
