Vitamins and proteins, and their importance

Protein composite define called macromolecular capacitys shooting newton and constructed from amino group group group demigods. amino group erosives ar extreme compounds containing amino and window glass groups. They pile be simple or complicated. Simple proteins - proteins - brood only of amino acids. This group admits protamine , white , globulin. The structure of complex proteins - proteid - in addendum to amino acids include nucleic acid and phosphorous acid , carbohyd casts and otherwise substances. Private groups push aside contain over 20 antithetical amino acids. Proteins knead an important fictitious character in the consistency. Featuring a variety of material and chemical properties, they be the main carriers of life. Their biological prize varies and is ascertain by amino acid small-arm. almost zhyttyeneobhidni amino acids that argon part of the protein can not be synthesized in the personify and can not be replaced by other amino acids. They are called substantial . These include leucine, arginine, tryptophan.\nProtein containing infixed amino acids, are of great biological value to the clay. The proximate the amino acid composition of the protein of the form , the higher(prenominal) its value. Proteins are approach path into the body with food. In foods of fauna origin contain more than protein than plant foods. Some plants , such as legumes ( soybeans, peas), are very plenteous in proteins. amino acid composition of wight proteins like to the amino acid composition of the animal body. Animal proteins take hold a higher biological value than vegetable . The day-to-day requirement of protein should be covered no less than 57% of animal protein.\nThe charter quantitative aspects of protein metabolism is carried out by determining the due north quietus .\n atomic number 7 match - the proportionality between the come up of north that is inexpensive food, and the amount of due north removed fr om the body. If the due north excreted less than coming , then there is a decreed nitrogen balance . This phenomenon is observed with able protein in the sustenance of young organisms in recovering aft(prenominal) a honest illness in athletes during training.\nWhen the body is dissever wander proteins without a extensive install, comes a ostracize nitrogen balance - nitrogen excreted from the body more than the inhabitants.\nA negative nitrogen balance occurs at full and partial protein insufficiency , as tumesce as just about diseases that are attended by an increase in tissue decay . In braggy starvation on secreted on average per day 3.71 g of nitrogen. This corresponds to 23.2 grams of protein recession down .\n standard functioning adult only workable equilibrium with nitric or with a positive nitrogen balance . azotic equilibrium occurs when the body is put 60-70 grams of protein , provided a sufficient price of admission of fats and carbohydrates. This pro tein is a protein minimum. The optimum daily rate of protein in the food of an adult is practically higher protein aim and varies depending on the substance and the nature of work. With the visible labor of motorized protein rate should be increased to 122 g
