Vitamin C

1.Vitamin C can be transformed into semi dehydroascorbic acid and dehydroascorbic acid by supplying electrons step by step. It can scavenge supernegative oxygen ion (O2 -), hydroxyl radical (OH -), organic radical (R -) and organic peroxy radical (roo -); The free radical of tocopherol can be reduced to tocopherol again, and the free radical of ascorbic acid can be reduced to ascorbic acid by NADH2 system under certain conditions.

2.Vitamin C is involved in the metabolism of amino acids, synthesis of neurotransmitters, synthesis of collagen and tissue intercellular matrix. It can reduce the permeability of blood vessels, accelerate the coagulation of blood, stimulate the coagulation function, promote the absorption of iron in the field, reduce blood lipid, increase the resistance to infection, participate in the detoxification function, and has the effect of antihistamine and preventing the formation of carcinogens.

3.Vitamin C can improve human immunity, high concentration of vitamin C helps to reduce cystine in food protein to cysteine, and then synthesize antibodies. In addition, vitamin C can promote the absorption of iron. Therefore, the absorption of iron is promoted. In addition, vitamin C can also make the sulfhydryl group of ferrous complexing enzyme in the active state, so as to play an effective role, so vitamin C is an important material to enhance the human immune ability.
