Vitamin C is an important substance in the human body and is also a substance that is very beneficial to human health. Of course, many people have certain misunderstandings about vitamin C supplementation, the most common of which is that vitamin C cannot be taken during the day. In fact, vitamin C is not photosensitivity and has the effect of inhibiting melanin deposition, so there is no problem in taking vitamin C during the day. Let me introduce to you the functions of vitamin C! 1. Participate in hydroxylation reaction Hydroxylation reaction is a necessary step in the synthesis or decomposition of many important substances in the body. Vitamin C must be involved in the hydroxylation process. 1. Promote collagen synthesis. When vitamin C is deficient, collagen synthesis is impaired, leading to scurvy. 2. Promote the synthesis of neurotransmitters (5-hydroxytryptamine and norepinephrine). 3. Promote steroid hydroxylation. Patients with high cholesterol should supplement adequate amounts of vitamin C. 4. Promote the hydroxylation and detoxification of organic matter or poisons. Vitamin C can increase the activity of mixed function oxidase and enhance the detoxification (hydroxylation) process of drugs or poisons. 2. Reduction Vitamin C can exist in the body in either an oxidized or reduced form, so it can act as a hydrogen donor or a hydrogen acceptor, playing an important role in the redox process in the body. 1. Promote antibody formation. High concentrations of vitamin C help reduce cystine in food protein to cysteine, which in turn helps synthesize antibodies. 2. Promote iron absorption. Vitamin C can reduce the difficult-to-absorb trivalent iron into easily absorbed divalent iron, thereby promoting the absorption of iron. In addition, it can also make the sulfhydryl group of ferrous chelating enzymes and other enzymes in an active state so that they can play their role effectively. Therefore, vitamin C is an important auxiliary drug for the treatment of anemia. 3. Promote the formation of tetrahydrofolate. Vitamin C can promote the reduction of folic acid to tetrahydrofolate and then exert its effect, so it also has a certain therapeutic effect on megaloblastic anemia. 4. Maintain the activity of sulfhydryl enzymes. 3. Other functions 1. Detoxification. Supplementing the body with a large amount of vitamin C can alleviate the toxic effects of heavy metals such as lead, mercury, cadmium, and arsenic on the body. 2. Prevent cancer. Many studies have shown that vitamin C can block the synthesis of carcinogens N-nitroso compounds and prevent cancer. 3. Eliminate free radicals. Vitamin C can eliminate free radicals such as supernegative oxygen ions, hydroxyl free radicals, organic free radicals and organic peroxides in the body by gradually donating electrons to convert into semi-deoxyascorbic acid and dehydroascorbic acid; it can reduce tocopherol free radicals to tocopherol. The ascorbic acid free radicals generated by the reaction can be reduced to ascorbic acid by the action of NADH2 system enzymes under certain conditions. |
