Vitamin c Introduction
The structure of vitamin C is similar to glucose, which is a kind of polyhydroxy compound. The two adjacent enol hydroxyl groups in the second and third positions of the molecule are easily dissociated and released H+, so it has the property of acid, also known as ascorbic acid. Vitamin C has a strong reducibility and is easily oxidized into dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function, but if dehydroascorbic acid continues to be oxidized and diketogluconic acid is generated, the reaction is irreversible and completely loses its physiological efficiency.
Vitamin c Function
1. Foods and Cosmetics: To prevent oxidation and extend the shelf-life of foods or cosmetics
2. Health Care: Anti-aging and skin whitener, Enhance immunity
3. Pharmaceutical: Guard against Cataract and Osteoporosis , mitigate the sickness of menopause, protect liver from damnification
