Vitamin C, also known as vitamin C, is a polyhydroxy compound with the chemical formula of c6h8o6. Its structure is similar to that of glucose. The two adjacent enol hydroxyl groups on the second and third positions of its molecule are easy to dissociate and release H +, so it has the property of acid, also known as L-ascorbic acid. Vitamin C has strong reducibility and can be easily oxidized to dehydroascorbic acid, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function. However, if dehydroascorbic acid continues to oxidize to produce diketoglutaric acid, the reaction will be irreversible and completely lose its physiological function.
Vitamin C can resist oxidation and delay aging. 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. It has a strong function of scavenging free radicals.
Vitamin C can promote the absorption of iron in human body, so as to treat anemia. Vitamin C can reduce the hard to absorb trivalent iron into easy to absorb bivalent iron, so as to promote the absorption of iron. In addition, it 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 auxiliary drug for the treatment of anemia.
Vitamin C can also promote cell metabolism and help cells detoxify. Adequate intake of vitamin C can support cell nutrition, so that the cell is always in an active functional state, then it can maintain normal work, so as to ensure the normal function of all organs, as well as daily energy.
