Vitamin C is also called ascorbic acid, is a water-soluble vitamins. Main physiological function of a vitamin C to promote collagen biosynthesis. Conducive to faster wound healing tissue; 2, to promote the amino acids tyrosine and tryptophan metabolism and prolong life of the body. 3, to improve the iron, calcium and folic acid use. 4, to improve the fat and lipid metabolism, especially cholesterol, prevent cardiovascular disease. 5, to promote the growth of teeth and bones and prevent bleeding gums. ; 6, the external environment to enhance the body's anti-stress and immunity. Vitamin C drugs in a variety of reactions in the body, such as participation in redox processes in biological oxidation and reduction reactions and cellular respiration play an important role. From an organizational level, the main role of vitamin C and the synthesis of mesenchymal cells. Include collagen, tooth and bone matrix, and capillary endothelial cell conjugates. Therefore, when vitamin C deficiency caused by scurvy, the collagen synthesis associated with defects, showing wounds difficult to heal through, and capillary barrier broken tooth formation caused a lot of bleeding point bleeding point of fusion to form ecchymoses. Vitamin C and scurvy have a long history. Hippocrates was the first person mentioned in scurvy. He described the soldiers ulcerated gums, tooth loss. . . ; Early sea travel raises the importance of scurvy, the fleet left the port of 3-4 months, so the crew often suffered from scurvy, people began to find this is due to the lack of sea travel's sake fresh vegetables and fruits . In 1932 the British Medical precipitation from the lemon juice from the crystalline substance with anti-scurvy in 1933, Swiss scientists have synthesized vitamin C, also known as ascorbic acid. Modern research shows that VC is essential to human health: 1. Collagen synthesis requires vitamin C to participate, so the lack of VC, not the normal collagen synthesis, leading to cell junction barrier. Body composed of cells, stromal cells by cells to link them, stromal cells, a key component of collagen. Total body protein collagen 1/3 to generate connective tissue, constitute the body skeleton. Such as bone, blood vessels, ligaments, etc., determines the elasticity of the skin, protect the brain and contribute to human healing. 2. Scurvy. The strength of the vessel wall and VC has a lot. Capillaries are the smallest of all blood vessels, may have only a cell wall thickness, strength, flexibility is responsible for connecting cells with clay determined the role of collagen. When the body less than VC, easily broken capillaries, blood flow to adjacent tissues. This situation occurs in the skin surface, the resulting congestion, purple plaques; occur in the body and joint pain is caused by Zhang Tong. Serious situation in the stomach, intestines, nose, kidney, and periosteum following may have bleeding, and death. 3. Gingival recession, bleeding. Healthy gums tightly wrap each tooth. Gingival soft tissue, when the lack of protein, calcium, VC is easy to produce gingival recession, bleeding. 4. Prevention of atherosclerosis. Can promote the excretion of cholesterol, prevent cholesterol deposition in the arterial wall, or even dissolve the deposition of plaque. 5 is a powerful water-soluble antioxidants. Can protect other antioxidants such as vitamin A, vitamin E, unsaturated fatty acids, to prevent free radical damage to the human body. 6. Treatment of anemia. Make it difficult to absorb the reduction of ferric iron into ferrous iron, to promote universal absorption of iron, increased utilization of liver iron helps treat iron deficiency anemia. 7. Cancer. Rich in collagen to help prevent the spread of cancer; VC antioxidant against free radicals can damage the cells to prevent cell mutation; blocking the formation of nitrite and secondary amines strong carcinogenic nitrosamines. There have been deaths due to cancer patient's body found in patients with anatomical VC content is almost zero. 8. Protect the cells, detoxify, protect the liver. In human life activities, to ensure integrity of the cell and normal metabolism is essential. To this end, glutathione and enzymes play an important role. Glutathione is glutamic acid, cysteine ??and glycine peptide composed of the body have redox. It exist in two forms, namely, oxidized and reduced, but also the prototype for ensuring the integrity of cell membranes play an important role. VC is a powerful antioxidant, which itself is oxidized, leaving the reduction of oxidized glutathione to glutathione, thus playing the role of antioxidants. Enzymes are catalysts for biochemical reactions, some enzymes require free thiol (-SH) in order to maintain activity. VC enables disulfide (-SS) reduced to-SH, thereby enhancing the activity of enzymes play the role of antioxidant. From the above we can see, as long as the VC sufficient, then the VC, glutathione,-SH to form a portfolio of strong anti-oxidant, free radicals, preventing lipid peroxidation and toxic effects of certain chemical substances, protect the liver's detoxification capacity and normal cell metabolism. 9. Improve the body's immune system. White blood cells are rich in VC, when the body's white blood cells infected with the VC when the sharp decline. VC can enhance neutrophil chemotaxis and deformation capacity, improve disinfection. Promote the generation of lymphoblasts, raise the body to foreign and to identify and kill malignant cells. Involved in immunoglobulin synthesis. Improve CI complement esterase activity, increased production of complement CI. Promote the production of interferon, interfere with the virus mRNA transcription, inhibit virus proliferation. 10. Improve the body's emergency response capacity. Abnormal stimulation by the human body, such as pain, cold, hypoxia, stimulate the spirit of strong will to resist the abnormal stimulation caused tension. The state associated with a range of physical, including sympathetic, adrenal medulla and cortex hormone secretion increased. Adrenal medulla secretes epinephrine and norepinephrine are transformed from tyrosine, in the second process requires the participation of VC. Into the body of vitamin C quickly distributed in a tissue and organ, under normal circumstances, the body of 1500 mg of vitamin C library. Most of the excess with the urine, with small stool, sweat and respiratory discharge. However, in the case of infection, the body is usually required 20 --- 40 times as much, and all drugs will destroy the body's VC. So in the case of state human body is a very useful supplement VC. Davis, American nutritionist asked for a study of medical nutrition, should the VC in the standing when the writer drugs for any disease initially can be taken. Most doctors say: "Of course, much safer than any aspirin", the first continuous use of adequate than the use of small doses have a better effect.
