The function of vitamins.

Of course, everyone knows that for the normal functioning of the body needed vitamins.We regularly talk about the need for consumption of fruits and vegetables, they say, they are replete with useful substances.We often hear that during the season of "domination" of viruses and bacteria, and also after physical and mental stress, we need to fill the shortage of vitamins, micro and macro.And sometimes the simple inhabitant clue why.The thing is that not everyone knows what is the function of vitamins in the human body.

Who needs first?

Certainly few people dare to dispute the fact that the nutrients necessary for everyone.Function of vitamins - is to maintain the normal operation of the body.Their deficiency leads to a weakening of health, which entails different types of disease.One way or another, but there are categories of people who are essential nutrients: children, adolescents, the sick, pregnant and lactating women.

However, this does not mean that other people can not do without them.The fact that another important function of vitamins - is strengthening the immune system, which means that everyone who cares about their health, is obliged to take them regularly.However, before we consider the role played by the aforementioned substances in our body, to determine that they are.

What do we know about them?

vitamins are a special kind of organic compounds that the body can not produce on their own.Naturally, this disadvantage is compensated with food.

It should be noted that the function of vitamins varies depending on the structure of chemical compounds.In particular, there exist acids such as for example vitamin "C".There are also salt - vitamin "B15."Vitamin A is one of the alcohols of high molecular weight, moreover, are sensitive to oxygen and heat.

One part of vitamins is a homogeneous chemical compounds, and the other - Vitamins «B», «C», «D» - consists of many chemicals.

How do they work?

Still move on to the main question: "What are the functions of vitamins"?

Almost all of them have a low molecular weight.What does it mean?Only the fact that the main function of vitamins - a complex construction of all the processes occurring in our body.Although we need only a small concentration of nutrients, vitamins we need, above all, because they play a vital role in metabolism, which is a complicated conversion system food coming from the outside in the form of proteins, carbohydrates, fats, salts, vitaminsand water.First, food is crushed, then changes in the organic digested and transformed in the final stage in the construction material for the formation of new molecules or converted into energy.It must be stressed that the delivery of building material for the cells and providing them with energy - it is not the function of vitamins.They only control to the metabolic processes in the body proceeds normally.Due to the above nutrients in our body may be biochemical reactions.Their effect is equivalent to that of water, which, having a sparse structure, can seep into all tissues and organs.

And after all, why they are needed?

in the figurative sense, the body is a huge chemical company which carried out the production of energy and the production of building material for the body's cells.

Vitamins - it is an integral component of all living things, they need to activate the chemical reactions in our tissues.In other words, act as a catalyst, not taking direct part in these reactions.In particular, the "trace" food cleavage into soluble and simple components, "control" to simple substances are transformed into a source of energy.Certainly, it is unique and vital functions of vitamins in the human body.They seem to act as managers: direct participation in the work is not accepted, but their presence provides a smooth and normal activities of life systems.Here are some invaluable help provide for our health vitamins function in the body which are not limited.On top of that, they activate the formation of enzymes.In its role as a coenzyme, vitamin is very mobile: under its influence all processes in the body take place very quickly, for example, when it comes to digestion of starch.

As noted above, each group of the above nutrients affects certain organs and tissues, and their deficiency can lead to health problems.We have examined two main questions, namely: why is so important for the human vitamins, vitamins function.Beriberi, unfortunately, is not uncommon.

Vitamin "A»

First of all, he contributes to a young body, improves the condition of the epithelium, influences the formation of the skeleton.

in symbiosis with vitamin C, vitamin A reduces the level of lipids and cholesterol in the blood.Deficiency of this substance leads to liver dysfunction, adrenal and thyroid glands.

Vitamin B1

Controls fat, protein metabolism, fatty acid synthesis, and activates the process of converting carbohydrates into fat.Moreover, vitamin B1 improves the functioning of the digestive organs, and heart.

Vitamin B2

This organic compound contributes to the transformation of fats and carbohydrates into energy.This amount depends on its temperament and energetic person.

Vitamin B3

It also has beneficial effects on the thyroid gland, liver and adrenal glands.Also, vitamin B3 normalizes the function of the nervous system, its lack of a person has a sense of anxiety.

Vitamin B6

This compound is involved in the metabolic processes and the formation of enzymes.Besides, vitamin B6 controls lipid metabolism.

Vitamin B12

It has antianemic effect and regulates metabolism, promotes normal growth of the child.

Vitamin C

Performs redox function and is involved in protein metabolism.It also improves the immune system and normalizes the psycho-emotional state of a person.

Vitamin D

This element controls the deposition of phosphorus and potassium phosphate in bone tissues, its deficiency leads to tooth decay.

In addition, it improves the function of the intestinal absorption of phosphorus and calcium.

Vitamin E is vital for pregnant women, as it promotes the normal development of the fetus.It also activates the process of production of the seminal fluid.

Vitamin PP

normalizes the digestive system, improves the function of the liver: helps pigment, glycogen accumulation and excretion of toxins from the body.
