VITAMINS

N.I. Lunin discovered that mice die if they are fed

a food mixture consisting of purified foods. If you add 1 ml of milk to the diet, the mice remain healthy.
In the years 1911-1912. Polish scientist Kazimir Funk has isolated a preparation from bran and named it a vitamin. From this time, intensive study of vitamins began . Vitamins are denoted by the letters of the Latin alphabet A, B, C, D, E, F, P, etc. At present, most of the vitamins are isolated in pure form or synthesized and used as medicines.

own. Thus we must obtain them from the foods we

eat, or via vitamin supplements.
They are essential for providing good health and are necessary for many life functions.
They are regulator molecules. They regulate normal growth and development.

include vitamins A, D, E, K.  
Water-soluble are vitamins

of group B: B1, B2, B5 (pantothenic acid), B6, B12, BC (folic acid), vitamins C, H (biotin), PP (nicotinic acid).
 Several of these vitamins (B1, B2, B6, B5, folic acid, vitamin K) are synthesized by the normal microflora (bacteria) of the intestine, but in a very small amount, significantly inferior to the daily needs of the human body.

origin, especially its abundant in cod liver oil and cod

liver and halibut. Plants contain provitamin A - carotene, which in the body of animals turns into vitamin A. It is necessary for the treatment of infectious diseases and for people whose work is related to vision stress (drivers, snipers, etc.).

of vitamins, consisting of several species. The most famous are:
В1

В2
В6
В12

of rice, brewer's yeast, liver, pork, nuts, whole grains of

cereals. Thiamin is part of the enzymes involved in carbohydrate metabolism, and if it is deficient, not only carbohydrate, but also fat and protein metabolisms are disrupted

oxidation-reduction processes in all cells of the body.
It is abundant

in the liver, kidneys, yeast and other plant and animal products.

acids (promotes the action of enzymes).
It is found in

rice bran, beans, yeast, kidneys, liver, meat.

the function of hematopoiesis, it is used as a medicinal

preparation in the treatment of malignant anemia. Cobalamin is synthesized by bacteria of the intestine, in large quantities is contained in the liver of cattle and chickens.

promotes better use of oxygen by body tissues - a

means of eliminating hypoxia, or oxygen deficiency.
This vitamin is found in the seeds of many plants.

plant food. It is abundant in berries of dog rose,

black currant, lemons, etc. It plays an important role in carbohydrate and protein metabolism (it participates in oxidation-reduction reactions, entering into the composition of enzymes).

fish oil.
In plants and human skin there is a

substance ergosterol, which under the influence of ultraviolet rays turns into vitamin D

processes. In a small amount, nicotinic acid is synthesized by

intestinal bacteria, but this is not enough and it must be supplemented with food. Especially a lot of vitamin PP is found in yeast, fresh vegetables, meat, but little in corn.

Vitamin K is found in the green leaves of plants,

as well as in those parts of plants that contain chlorophyll, a lot of it in berries of mountain ash, as well as in the liver.

protein metabolism, muscle contraction, strengthens the walls of vascular tissue.

It is soluble in fats, it does not decompose on boiling.
It is found in both animal and vegetable products: egg yolk, liver, wheat germ, unrefined cottonseed, soybean, corn oil, dog rose, bananas, apples, pears, lemons and oranges.
