Vitamins. Their role.
For the first time revealed the role of vitamin E in the reproductive process in 1920. Vitamin E plays a preventive role - he can not restore the pre-existing damage. Participants in some studies, which were not found any anti-cancer effectiveness of vitamin E for many years smoked or irresponsible attitude to healthy eating. No drugs or vitamins are not able to reverse the tissue destruction caused by decades of unhealthy lifestyles. For example, the daily intake of 400 between. units. Vitamin E can prevent the conversion of nitrite (certain substances that are present in smoked and pickled foods) into carcinogenic nitrosamines, but does not lead to a backlash conversion of nitrosamines to nitrites.
For the first time vitamin A has been isolated from carrots, so the British carrot (carrot), there was a name of vitamin A - the carotenoids. Vitamin A is involved in redox processes, regulation of protein synthesis, promotes normal metabolism, the functions of cellular and subcellular membranes and plays an important role in the formation of bones and teeth, as well as fat, is essential for growth of new cells, slows the aging process.
Vitamin D group formed under the action of ultraviolet radiation in the tissues of animals and plants from sterols. External use of vitamin D3 for psoriasis reduces the characteristic scaly skin. Vitamin D3 is involved in regulation of blood pressure (particularly in pregnant women with hypertension) and heart rate. Vitamin D inhibits the growth of cancer cells and that makes it effective in the prevention and treatment of breast, ovarian, prostate, brain, and leukemia.
Vitamin K is fat-soluble vitamin stored in small quantities in the liver, it breaks the light and in alkaline solutions. Vitamin K is also synthesized in the human gut microflora. It should be remembered that despite the fact that vitamin K is in a wide range of vegetable foods, however, because vitamin is fat soluble, so that the process of digestion was carried out normally (no matter whether it is a product of bacterial activity or derived from food) in the intestine should be a little fat.
Vitamin B1 - water-soluble vitamin, easily destroyed by heat treatment in an alkaline environment. Vitamin B1 is required for oxidative decarboxylation of keto acids (pyruvic and lactic), the synthesis of acetylcholine, it is involved in carbohydrate metabolism and associated energy, fat, protein, water-salt metabolism, has a regulating effect on the trophic and the nervous system.
Riboflavin is destroyed by light, is poorly soluble in water (solubility increases with decreasing pH) and alcohol. Riboflavin is necessary for the formation of red blood cells and antibodies for cellular respiration and growth. It facilitates the absorption of oxygen by cells of the skin, hair and nails. It improves the condition of the organ of vision, taking, along with vitamin A, participate in the process of dark adaptation, reduces eye fatigue and plays a major role in preventing cataracts.
Activity of vitamin B6 has a group of compounds, pyridine derivatives (pyridoxine (piridoksol), pyridoxal and pyridoxamine), collectively called pyridoxine. Plays an important role in metabolism, essential for the normal functioning of the central and peripheral nervous system is involved in the synthesis of neurotransmitters. In the phosphorylated form provides a process of decarboxylation, transamination, deamination of amino acids involved in the synthesis of proteins, enzymes, hemoglobin, prostaglandins, exchange of serotonin, catecholamines, glutamate, GABA, histamine, and improves the use of unsaturated fatty acids, lowers cholesterol and blood lipids, improves myocardial contractility, contributes to the transformation of folic acid in its active form, stimulates hematopoiesis.
Vitamin B12 - the only water-soluble vitamin that can accumulate in the body - it is deposited in the liver, kidneys, lungs and spleen. Vitamin B12 is involved in transmethylation, hydrogen transport, activates the synthesis of methionine. Leveraging the synthesis and the ability to accumulate protein in the body, uianookbalamin also provides an anabolic effect.
Vitamin C - a powerful antioxidant. It plays an important role in the regulation of redox processes involved in the synthesis of collagen and procollagen, the exchange of folic acid and iron, as well as the synthesis of steroid hormones and catecholamines. Vitamin C improves the body\'s ability to absorb calcium and iron, remove toxic copper, lead and mercury.
Vitamin PP exists in two forms - nicotinic acid and nicotinamide. Vitamin PP - Part B-complex, which is crucial for energy production and maintaining well-being on many levels, especially for heart health and optimal circulation. He has been involved in more than half a hundred reactions, in which sugar and fat are converted into energy. It is also necessary for metabolism of amino acids and is involved in the conversion of fats into substances called eicosanoids - hormone-like agents that control the metabolic pathways of the body.
Biotin plays an important role in carbohydrate metabolism: it interacts with the hormone insulin and the pancreas, thereby, stabilize blood sugar. In addition, he participates in the production of glucokinase - a substance that triggers the process of glucose metabolism Biotin also helps to digest protein, is involved in the decomposition of fatty acids and fat burning. In exchange, he or she is an important ally of the other B vitamins: folic acid, pantothenic acid, vitamin B12.
Pantothenic acid gets its name from the Greek pantothenic, which means everywhere, because of its extremely wide distribution. An important property of vitamin B5 is its ability to stimulate production of adrenal hormones - glucocorticoids, which makes it a powerful tool for the treatment of diseases such as arthritis, colitis, allergies and heart disease.
Stimulates the exchange of protein in the body, normalizes liver function, contributing to the regeneration of hepatocytes.
Orotic acid is involved in the synthesis of methionine, an exchange of folic acid and pantothenic acid. Orotic acid improves reproductive health, a positive effect on fetal development during pregnancy.
Vitamin B9 - water-soluble vitamin, it is highly soluble in water at alkaline values of pH. Easily destroyed during cooking and light. Folic acid supports the immune system, contributes to the formation and functioning of white blood cells. Folic acid has been actively involved in the processes of regulation of the functions of blood, has antianemic impact in macrocytic anemia. Also have a positive effect on bowel function and liver, increases the content of choline in the liver and prevents it from fatty infiltration.
