Protein Calculator

Many people know that athletes should eat protein - eat meat, fish, eggs, and even take special protein supplements. But why do you need protein, and even in such quantities? Didn't vegetarians prove by their example that you can do without protein? Let's figure it out. Proteins (polypeptides) are the most numerous, most diverse and of paramount biopolymers. Protein molecules contain atoms of carbon, oxygen, hydrogen, nitrogen and sometimes sulfur, phosphorus and iron. Protein monomers are amino acids. The human body contains 22 amino acids: the body can synthesize 13 amino acids on its own from the available building material, and 9 of them it can get only with food.

Proteins are the main building blocks of the body. It is involved in the creation of muscles, tendons, organs and skin, and is also needed for the production of enzymes, hormones, neurotransmitters and various molecules that perform many important functions. In addition, proteins have other important functions: Catalytic. Proteins are the main component of all known enzymes. Hormonal. Most hormones are proteins. Protective. Lack of protein weakens the defense function because the immune system cannot function adequately. Transport. Proteins are involved in the transport of oxygen, carbohydrates, fats, some vitamins and minerals.
