They are chemicals necessary for normal growth and prevent certain diseases. Vitamins are contained in food both animal and vegetable origin, but are more abundant in fresh vegetables (spinach, chard, lettuce, carrots, beets, etc.) and fruits.
Classification of vitamins:
Are classified according to their ability to dissolve in fat (fat-soluble vitamins) or water (water soluble vitamins). The fat-soluble vitamins, A, D, E and K, are consumed with foods that contain fat and because of that can be stored in body fat, you need not take them every day. Water-soluble vitamins, the eight group B and vitamin C, cannot be stored and therefore must be consumed frequently, preferably daily (except for some B vitamins, as we shall see later).
Types of vitamins and their role in our body:
Vitamins are involved in the formation of hormones, blood cells, nervous system chemicals and genetic material. The various vitamins are not chemically related, and most of them have a different physiological action. Usually act as catalysts, combining with proteins to create metabolically active enzymes which in turn important chemical reactions occur throughout the body. Vitamins without many of these reactions would take longer to occur or cease altogether.
-Vitamin A: Is a primary alcohol pale yellow carotene derived. The body gets vitamin A in two ways. One is manufacturing it from carotene, a vitamin precursor found in vegetables such as carrots, broccoli, pumpkin, spinach, cabbage and sweet potatoes. The other is absorbing and list of organisms that eat plants. Vitamin A is found in milk, butter, cheese, egg yolk, liver and fish liver oil.
Excess vitamin A can interfere with growth, stop menstruation, harm to red blood cells and cause rashes, headaches, nausea and jaundice.
-Vitamins B: Also known by the name of B vitamin complex, are fragile, water-soluble substances, several of which are especially important to metabolize carbohydrates or sugars.
Thiamine or vitamin B1 is a colorless crystalline substance, acts as a catalyst in the metabolism of carbohydrates, pyruvic acid metabolize allowing and causing carbohydrates release their energy.
Riboflavin or vitamin B2, as thiamine, acts as a coenzyme, i.e., must be combined with a portion of another enzyme to be effective in the metabolism of carbohydrates, fats and particularly in the metabolism of proteins involved oxygen transport. Also acts to maintain the mucous membranes.
The nicotinamide or vitamin B3, vitamin B complex whose structure corresponds to the amide of nicotinic acid or niacin, acts as a coenzyme to release energy from nutrients. Vitamin B6 or pyridoxine is necessary for the absorption and metabolism of amino acids is also known. It also acts in the use of body fat and the formation of red blood cells or erythrocytes.
Cobalamin or vitamin B12, also known as cyanocobalamin, is one of the recently isolated vitamins. It is necessary in trace for forming nucleoproteins, proteins and red globules, and the nervous system.
Other B vitamins or folacin Folic acid is a coenzyme necessary for the formation of structural proteins and hemoglobin; its failure in humans is very rare.
-Vitamin C: is important in the formation and maintenance of collagen, the protein that holds many body structures and represents a very important role in the formation of bones and teeth. It also promotes the absorption of iron from plant foods.
-Vitamin D: is required for normal bone formation and retention of calcium and phosphorus in the body. It also protects the teeth and bones against the effects of low calcium intake, making a more effective use calcium and phosphorus.
-Vitamin E: is found in vegetable oils, wheat germ, liver and green vegetables. This vitamin is involved in the formation of red blood cells, muscles and other tissues and in preventing the oxidation of vitamin A and fats. It is found in vegetable oils, wheat germ, liver and green leafy vegetables.
-Vitamin K: is necessary mainly for blood clotting. Supports the formation of prothrombin, an enzyme necessary for the production of fibrin clot. The richest sources of vitamin K are alfalfa and liver of fish, which are used to make preparations with concentrations of this vitamin. Dietary sources include all leafy green vegetables, egg yolk, soybean oil (soybean) and liver.
Diseases by lack of vitamins:
-Vitamin A:One of the first signs of failure is night blindness (difficulty in adapting to darkness). Other symptoms are excessive dry skin; lack of secretion of the mucous membrane, causing susceptibility to bacterial invasion, and dry eyes due to malfunction of the tear, a major cause of blindness in children in less developed countries.
-Thiamine or Vitamin B1: The lack of thiamine produces beriberi, which is characterized by muscle weakness, inflammation of the heart and leg cramps and in severe cases, heart attack and death.
-Riboflavin or vitamin B2: The failure of this vitamin can be complicated if there is lack of other vitamins of group B. Its symptoms, not as defined as the lack of thiamine, are skin lesions, especially around the lips and nose, and sensitivity to light.
-Niacin or nicotinic acid (vitamin B3): The failure causes pellagra, whose first symptom is a rash similar to sunburn wherever the skin is exposed to sunlight. Other symptoms include red, swollen tongue, diarrhea, mental confusion, irritability and, when the central, depression and mental disorders nervous system is affected.
-Pyridoxine or vitamin B6: pyridoxine deficiency is characterized by skin disorders, cracks at the corners of the lips, thicken tongue, convulsions, dizziness, nausea, anemia and kidney stones (see Litiasis).
-Cobalamin or vitamin B12: cobalamin insufficiency is often due to the inability of the stomach to produce a glycoprotein (intrinsic factor) that helps to absorb this vitamin. The result is a pernicious anemia, with the characteristic symptoms of bad production of red blood cells, defective synthesis of myelin (nerve sheath) and loss of the epithelium (membranous cover) of the intestinal tract.
-Vitamin C: Scurvy is the classic manifestation of serious lack of ascorbic acid. Its symptoms are due to the loss of the cementing action of collagen, and among them are bleeding, loss of teeth and cellular changes in the bones of children.
-Vitamin D: Bone Deformation Rickets may be the result of inadequate dietary intake of vitamin D, or an inadequate supply of solar ultraviolet radiation.
-Vitamin K: deficiency of this vitamin can cause slow blood clotting.
