Protein is one of the most important places among the organic elements of a living cell.It is almost half of the cell mass.In humans, there is a constant exchange of proteins that come with food.The digestive tract is carried breakdown of proteins to amino acids.Recent penetrate into the blood, and passing through the cells and blood vessels of the liver, enter the tissues of the internal organs, which are synthesized in the back of the organ-specific proteins.
protein metabolism
The human body uses protein as a plastic material.His need is determined by the minimum volume that balances protein loss.The body of the adult healthy human metabolism of proteins occurs continuously.In case of inadequate intake of these substances from food ten of the twenty amino acids may be synthesized by the body, while the other ten are indispensable and must be replenished.Otherwise there is a violation of protein synthesis, which leads to growth inhibition and weight loss.It should be noted that if there is not at least one essential amino acid the body can not live a normal life and function.
stages of protein metabolism
Protein metabolism in the body is the result of supply of nutrients and oxygen.There are specific metabolic steps, the first of which is characterized by enzymatic digestion of proteins, carbohydrates and fats to soluble amino acids, monosaccharides, disaccharides, fatty acids, glycerol, and other compounds, after which they are absorbed into the blood and lymph.In the second stage the nutrients are transported in blood and oxygen to the tissues.When this occurs before the end of their cleavage products, and the synthesis of hormones, enzymes, and integral components of the cytoplasm.Upon cleavage agents energy is released, which is necessary for the synthesis of natural processes and the normalization of the whole organism.The above steps of removing an end of exchange of proteins from cells of the final products, and their transport and release of the lungs, kidneys, intestines and sweat glands.
benefits of proteins for human
for the human body is very important receipt of complete proteins, because only they can be synthesized from specific substances.A special role in the metabolism of proteins plays a child's body.After all, it needs a large number of new cells to grow.If insufficient intake of proteins the human body ceases to grow, and its cells updated much slower.It includes a full-fledged animal proteins.Of these, of particular value are the proteins of fish, meat, milk, eggs and other similar foods.Defective is mostly found in plants, so the diet must be formulated so as to meet all the needs of the organism.When an excess of proteins over their breaks.This allows the body to maintain the required chemical equilibrium.Protein metabolism is very important for human life.When it is violated the body begins to consume protein of their own tissues, leading to serious health problems.Therefore, you should take care of yourself and serious approach to the selection of food.
