List of various vitamin functions

Vitamins are a huge family. There are dozens of vitamins known so far, which can be broadly divided into fat-soluble and water-soluble categories. The former includes vitamins A, D, E, and K. The latter includes vitamin B and Vitamin C, as well as many "retinoids".
The vitamins currently found in medicine are:
Fat-soluble vitamins Vitamin A: maintains normal vision, prevents night blindness; maintains healthy epithelial cells; promotes growth and development; increases resistance to infectious diseases; prevention and treatment of dry eye disease.
Vitamin D: regulates the metabolism of calcium and phosphorus in the human body, promotes absorption and utilization, and promotes bone growth.
Vitamin E: maintain normal fertility and normal muscle metabolism; maintain the integrity of the central nervous system and vascular system.
Vitamin K: hemostasis. It is not only the main component of prothrombin, but also can promote the liver to produce prothrombin. Vitamin K deficiency in children water-soluble vitamins vitamin B1: to maintain circulation, digestion, nerve and intramuscular normal function; adjust the stomach Intestinal function; coenzymes that form decarboxylase, participate in sugar metabolism; can prevent beriberi.
Vitamin B2: also known as riboflavin. Nucleus is a component of many important coenzymes in the body. These enzymes can transfer hydrogen in the process of metabolism of substances in the body. It is also necessary for protein, sugar, fatty acid metabolism and energy utilization and composition. Substances. Can promote growth and development, protect eyes, skin health.
Pantothenic acid (vitamin B5): anti-stress, anti-cold, anti-infection, prevent the toxicity of certain antibiotics, eliminate postoperative abdominal distension.
Vitamin B6: plays an important role in protein metabolism. Treatment of neurasthenia, dizziness, atherosclerosis and so on.
Vitamin B12: anti-fatty liver, promote the storage of vitamin A in the liver; promote cell development and body metabolism; treatment of pernicious anemia.
Vitamin B13 (lactate clear).
Vitamin B15 (panitine): Mainly used for anti-fatty liver, increasing tissue oxygen metabolism rate. Sometimes used to treat coronary heart disease and chronic alcoholism.
Vitamin B17: Very toxic. Some people think that there is control and prevention of cancer.
Para-aminobenzoic acid: One of the most recently discovered vitamins in the vitamin B family. It is synthesized in the human body.
Inositol: One of the vitamin B family, like choline, is a lipophilic vitamin.
Vitamin C: Connects bones, teeth, connective tissue structure; has adhesion to various cells in the capillary wall; increases antibodies, enhances resistance; promotes red blood cell maturation.
Vitamin P.
Vitamin PP (nicotinic acid): It plays a role in transferring hydrogen during physiological oxidation of cells and has the efficacy of preventing and treating ecdysis.
Folic acid (vitamin M): Anti-anemia; maintain normal cell growth and immune system function.
Vitamin T: Helps the coagulation of blood and the formation of platelets.
Vitamin U: has an important role in the treatment of ulcers.
Vitamins are nutrients for the body, organic compounds needed for growth. If the body lacks vitamins, it will cause some kind of disease. Therefore, some people think that vitamins are nutrients, and the intake is "better and better." The more vitamins people need, the better? The answer is The key to rational nutrition is “moderate.” Excessive intake of certain vitamins is harmful to the body.
We know that vitamins can be broadly divided into water-soluble (vitamin B, C) and fat-soluble (vitamins A, D, K, etc.) two categories. Water-soluble vitamins are generally excreted in the urine, fat-soluble Vitamin A or D, the excess can not be excreted. This gives people an impression that water-soluble vitamin foods are more harmless, some people advocate daily oral vitamin C 3-5 grams to achieve the purpose of health care. In fact, this is harmful, Experiments have confirmed that long-term daily intake of more than 1g of vitamin C can cause oxalic aciduria, hyperuricemia, and hyperlipidemia. Some people may develop rash, edema, and blood pressure drop, nausea. In fat-soluble vitamins, vitamins A poisoning caused by excessive use of vitamin A and vitamin D is the most common. Vitamin A excess causes sleeplessness, wheezing, dizziness, hair loss, nausea, and diarrhea. Vitamin D excess can cause loss of appetite, burnout, and constipation. Weight loss and low fever and so on.
Normal daily needs vitamin C50-100 mg, vitamin A2500-3000 international units, vitamin D300-400 international units.
In terms of nutrition, the so-called vitamins are substances that cannot be synthesized by the human body (or synthetic quantities cannot meet the needs) but are indispensable for the normal metabolic processes of the human body and regulate physiological functions. They are nutrients that must be supplied by food. There will be some typical clinical symptoms. So far, no deficiency has been found due to the lack of amygdalin, so these two substances can not be called vitamins at all.
Vitamin B15 and Vitamin B17 are food ingredients beneficial to human health proposed by some nutrition scholars abroad, and they are called vitamins. However, they have not been recognized by scholars worldwide. Recent studies have shown that vitamins have some special functions. , Such as the role of pantothenic acid regulation, folic acid and vitamin B12 to reduce the role of DNA loss, folic acid plus B6 beneficial cardiovascular and so on.
