Ascorbic acid

Ascorbic acid (Acidum ascorbinicum, Acidum ascorbicum, vitamin C) is contained in a variety of plant foods. Ascorbic acid is involved in the regulation of metabolic processes of the body, the permeability of capillaries, the blood clotting, and other Daily need in ascorbic acid for adult 70 - 120 mg

Vitamin C is the most unstable of all the vitamins. He highlighted in chemically pure form, is shaped crystals and is called ascorbic acid. With a deficiency, or scurvy, known as scurvy. Hence the name of the vitamin C - ascorbic acid, that is acid, warning the emergence of scurvy.
The presence in food of vitamin C is necessary only for humans, monkeys and Guinea pigs. In the body other mammals, the formation of this vitamin.
The main sign of lack of content in the body of vitamin C is a tendency to hemorrhage, which are associated with changes in the tiny blood vessels (capillaries. This decreases the strength of the capillary wall, increases its permeability, through such wall easily passes the blood, which leads to bleeding. With a lack of vitamin C appears bleeding gums, bleeding in the skin, and in more severe cases, in the thick of muscle, in the cavity of the joints, and internal organs. Changes are also teeth, bones and other organs. The teeth become brittle bone strength is broken, broken badly grow together, wounds not long healing. Vitamin C participates in all major processes occurring in the body. Scientists have found it important role in the metabolism of proteins.
Insufficient provision of the organism with vitamin C reduced resistance to infectious diseases. Vaccinations that make against infectious diseases, cause people suffering With-hypovitaminosis, much less pronounced rise protective forces of an organism, than in persons who receive enough vitamin C.
The long absence of vitamin C in the diet leads, as we know, to the development of C-deficiency - scurvy. This disease until recently was inevitable companion of wars, long voyages, during which people of many months were deprived of vegetables, fruits and fresh meat. Currently scurvy as a mass disease had relegated the past. However, it is still often disguised forms of lack of vitamin C, or otherwise With-gipovitaminozy state.
The main source of vitamin C, vegetables and fruits. Reduction in food during the winter and spring is the main cause of deficiencies which frequently occurs during these times of the year. The observed people in the spring months of fatigue, lethargy, irritability, bleeding gums, the appearance of the skin, as if for no apparent reason the so-called "bruises" - all this is nothing but the manifestation of s-hypovitaminosis. All these violations quickly pass, when man begins to take vitamin C.
It is important to know that the decrease in food vitamin C is observed not only in the absence of vegetables, but also by improper food preparation, during which you can collapse a significant part of this unstable vitamin.
The need for vitamin C in a healthy person is about 70 milligrams per day; it is increased in women during pregnancy and up to 100 milligrams and breast feeding up to 120 milligrams. With heavy physical labour, especially in adverse climatic conditions (Far North, in the hot desert and desert areas - the body needs to 120 milligrams of the vitamin. Insufficient and untimely provision of such increased needs may be one of the reasons for the development of hypovitaminosis.
Of great importance in the occurrence of a lack of vitamin C have diseases that violate the absorption of this vitamin and increases the destruction of his body. Such diseases include diseases of the stomach and intestines, infectious diseases, including tuberculosis. This is why all such patients need higher amounts of vitamin C.

Extensive destruction of vitamin C and increased need in it there are some diseases and in the use of medications (salicylic acid, sulfidina, antibiotics).
How to prevent the emergence of hypovitaminosis? This requires that food throughout the year contains enough vitamin. First of all it is achieved by use, if possible, throughout the year, fresh vegetables and fruits. From plant products much vitamin C is found in wild rose, green walnut, black currant, red pepper, oranges and lemons, fresh and pickled cabbage, tomatoes and other Relatively little vitamin C in potatoes, but it is used in large quantities and therefore becomes a major source of vitamin C in the diet.
Much poorer vitamin C products of animal origin. In the meat it is small, but the food is fresh meat is a good means of protecting from scurvy. Small amounts of vitamin C contained in milk, and in summer more than winter. Boiling milk significant part of vitamin C has been destroyed.
Vitamin C is well preserved by freezing some fruit and vegetables. Such products are a good source of vitamin C, provided they defrost before preparing food.
When storing vegetables vitamin C content is reduced. That is why in spring there is a necessity in the additional provision of the organism with vitamin C. For this purpose used drugs ascorbic acid and vitamin concentrates, produced vitamin industry in the form of tablets, coated tablets and syrups. The most valuable natural concentrates prepared from wild rose and black currant. In rose, in addition To vitamin C, still contains carotene, vitamin e and other vitamins.
Especially need a vitamin With children, pregnant and lactating women. In this regard, in our country, it is mandatory food fortification With vitamin C in nurseries, orphanages, children's homes, hospitals for children and adults, and in maternity hospitals. Great importance is the provision of vitamin C lactating women, as this in milk have increased vitamin C and simultaneously fat.
According to Professor A. L. Mantova, vitamin C has a therapeutic effect in arteriosclerosis. Not less important is the ability of ascorbic acid to neutralize the action on the organism of some industrial poisons.
