Introduction:
Vitamin C, also known as vitamin C, is a polyhydroxyl compound, chemical formula is C6H8O6. The structure is similar to glucose, and the two adjacent enol hydroxyl groups on the second and third positions in the molecule are easy to dissociate and release H+, so they have the property of acid, also known as ascorbic acid. Vitamin C is highly reductive and can be easily oxidized to dehydrogenated vitamin C, but its reaction is reversible. Moreover, ascorbic acid and dehydroascorbic acid have the same physiological function. However, if dehydroascorbic acid continues to be oxidized to produce diketoguloglycolic acid, the reaction will be irreversible and lose its physiological function completely.
Application :
Vitamin C can be oxidized or reduced in the body, so it can be used as a hydrogen donor or a hydrogen acceptor to play an important role in the process of REDOX in the body.

Promote antibody formation. High levels of vitamin C help reduce cysteine in food proteins to cysteine, which in turn leads to the synthesis of antibodies.
Promote the absorption of iron. Vitamin C promotes the absorption of iron by reducing unabsorbable ferric iron to easily absorbable ferric iron. In addition, still can make the sulfhydryl group such as ferrous complexase is in active state, so as to effectively play a role, so that vitamin C is an important auxiliary drug for the treatment of anemia.
Promote tetrahydrofolic acid formation. Vitamin C can promote folic acid reduction to tetrahydrofolic acid after play a role, so on megaloblastic anemia also has a certain effect.
Maintain sulfhydrase activity.
Detoxification. After supplementing a large amount of vitamin C in the body, the toxic effects of heavy metals such as lead, mercury, cadmium and arsenic can be alleviated.
Prevent cancer. Many studies have shown that vitamin C can prevent cancer by blocking the synthesis of the carcinogen N-nitroso compounds. Scavenge free radicals. Vitamin C can be transformed into semi-dehydrogenated ascorbic acid and dehydrogenated ascorbic acid by supplying electrons step by step to remove supernegative oxygen ion (O2-), hydroxyl radical (OH-), organic free radical (R-) and organic peroxy group (ROO-) in the body. The tocopherol free radical is rereduced to tocopherol, and the ascorbic acid free radical generated by the reaction can be reduced to ascorbic acid under the action of NADH2 system enzyme under certain conditions.
