Metabolism is a set of chemical transformations occurring in living organisms that ensure their growth, development, life processes, reproduction of offspring, and active interaction with the environment.
Plastic exchange is understood to mean such processes, during which new compounds and new structures characteristic of a given organism are created in cells.
Thiamine (B-1) – is involved in processes that ensure the normal activity of the central nervous system. Lack of it in food leads to severe illness (paralysis, convulsions), for therapeutic purposes it is used in cases of overwork and nervous exhaustion.
Amino acids through the blood capillaries of the villi enter the liver. Here, excess amino acids lose their nitrogen and are converted into fats and carbohydrates. In the cells of the amino acids build their own body proteins.
From the body into the environment are not displayed: amino acids, carbohydrates, oxygen.
Ascorbic acid (C) – plays a large role in the redox processes occurring in the body. Contained in wild rose, black currant, lemon, oranges, cabbage, green onions and other vegetables, fruits, berries.
Proteins are the main building blocks of cells, they are involved in blood coagulation (fibrinogen), gas transportation (hemoglobin). Perform the role of biocatalysts (enzymatic role).
Water is an environment of life processes. Where do the tissues of our body take water? They create it themselves. This internal water is constantly formed due to the oxidation of nutrients.
In the body, carbohydrates are the main source of energy. Digested, carbohydrates (starch, glycogen) is converted into glucose (sugar), which is absorbed into the blood.
Potassium salts, as well as sodium salts, affect the water content in the tissues. They support a weak alkaline blood environment. Potassium is necessary for normal excitability of the nervous and muscular systems.
Vitamin A (growth vitamin). In its absence, growth is delayed, vision is disturbed, dry skin is noted, and the body’s resistance to disease is reduced. In large quantities, it is found in butter, liver, fish oil, caviar, egg yolk, and milk.
Body proteins are built up from amino acid cells.
Muscles produce heat. Striated muscles – engines. in which chemical energy is converted immediately into mechanical. Energy in the form of heat is transmitted by blood to other tissues and evenly warms the body. Small involuntary muscle contractions cause shivering – the body increases the formation of heat.
The body is constantly breaking down protein. This produces water, carbon dioxide and nitrogen-containing substances, which are removed from the body through the kidneys, lungs and skin.
Obesity is not just fullness, it is a disease accompanied by metabolic disorders, the work of the heart, blood vessels, organs of motion. It is caused by unlimited consumption of fats, carbohydrates (confectionery, potatoes). Obesity reduces human performance.
