Proteins are not only important nutrients but also the largest component in the body, immediately after water, as they represent as much as 15% of body weight. Most of them are found in skeletal muscles, which explains the importance of protein in motion. In addition to movement, they also play an important role in the introduction and storage of other nutrients, in the catalysis of biochemical reactions and immune resistance.
Proteins are substances without which there is no living organism since all life processes are bound to them. They are integral parts of each cell. The organism therefore necessarily needs them. Plants are made from inorganic compounds that absorb them from the soil, animals, and man, and they must get it with food.
Proteins are an integral part of all body tissues. There are about 50,000 protein-containing substances in the body, and there are thousands of cells in each cell with different molecular structures .. Impressive, no? Only these two facts speak of their extraordinary meaning. But let’s go well in line.
Proteins are amino acid polymers. All proteins are made up of 20 different amino acids, which in different sequences connect in long chains. In all amino acids, four groups are bound to the central carbon atom. The first is the amine group NH2, the other is the carboxyl group -COOH, and the third bond C atom is bound hydrogen. A fourth place is already a secondary group or the radical, according to which the amino acids differ (physical and chemical properties).
Proteins are natural polymers that involve various amino acids or monomers. The chemical elements that make up the proteins are carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur and phosphorus. Proteins are the building materials of the body. They are an essential ingredient in each cell and are involved in the restoration of all organs. Protein compounds compile and control the brain, glands, nerves, hormones, and enzymes. Thousands of different protein compounds in the human body and the nutrients.
Enzymes are also proteins. Each protein is composed of amino acids, but always in a different ratio. Simple proteins (proteins) contain up to 20 amino acids. We say that some protein has a high biological value when the body can produce many of its proteins from it.
Proteins ARE DIFFERENT
Protein molecules also have a characteristic spatial form. They can be a helix or wrapped in a hat. The biological activity of proteins depends on their spatial form. By increasing the temperature, the spatial form of the protein molecule changes. Therefore, its structure and hence its biological function is changed. The phenomenon is called denaturation of the protein. Similarly, proteins also include alcohol, pH changes, heavy metal salts, and environmental radiation. These are toxins for proteins because they cause irreparable damage to their structure.
In the binding of amino acids, the amine group is superior to the carboxyl group (COOK), thereby clearing the water (dehydration).
The bond that arises is a peptide bond. At the splitting of the protein, the amino acid is already a molecule of water (hydrolysis).
When there are already two amino acids, the new compound is called a dipeptide; when the three tripeptides, the oligopeptide is a connection of 20 or more amino acids, The polypeptide is a link of 50 and more amino acids. Simple polypeptide chains are called proteins.
If the protein intake in the body is defective or if it is a poor quality protein, the muscle tissue begins to break down. This means that the body begins to take protein from the part where it is most. The body constantly needs a lot of amino acids that it extracts from protein, so if the body does not have enough protein, vital functions are limited, including energy and immune resistance.
How much protein should we eat each day?
The recommended daily protein intake is 59g / day for adult men and 47g / day for adult women. With age, the need for protein decreases slightly, but not significantly, about 1g every ten years, from the age of 50 years. More and more proteins also need children and pregnant women from the 4th month of pregnancy.
If our everyday diet is too unique, we begin to lack basic elements in the body. Different disorders can occur. The compounds of the body need our body to form the amino acids from which proteins are built. All necessary nitrogen compounds are obtained by consuming sufficient quantities of animal and plant proteins, such as meat, fish, eggs, cheese, beans …
THE DEVELOPMENT PROCESS INCREASES BEYAKOVIN
The foods that we eat with food digest into the main components-amino acids in the gastrointestinal tract. These come through the bloodstream to cells, where they begin to reconnect in different sequences and form new protein chains. The number of amino acids in the blood, regulate the liver. The amino acid, which the body does not need, changes in the liver into urine that is excreted in the urine. A certain amount of protein consumes the body as a source of energy and the formation of fats and carbohydrates.
We need proteins for growth and normal physical development. In the human body, proteins are formed and decomposed. Genetic engineering is a method for the laboratory preparation of proteins that humans need urgently.
