'\n\nProteins vsokomolekulyarne polymer, Nature, postroenne residues of aminic mordants, soedynennh amide (peptide) svyazyu? CO? NH?.\n distributively protein harakteryzuetsya spetsyfycheskoy amynokyslotnoy posledovatelnostyu and yndyvydualnoy spacial strukturoy (conformation). The care of proteins pryhodytsya at least 50% dry out tidy sum orhanycheskyh compounds zhyvotnoy cells. procedure protein underlies vazhneyshyh processes zhyznedeyatelnosty existence. metamorphosis substances (digestive corpse, respiratory and others) mshechnoe Reduction, nervnaya conduction cells and life sentence in prevalent nerazrvno svyazan with aktyvnostyu enzymes - passing circumstantial catalysts biochemically reactions yavlyayuschyhsya proteins. priming coat kostnoy and soedynytelnoy woven, wool, rohovh formations sostavlyayut strukturne proteins. Ona equivalent skeleton in the closet formyruyut kletochnh organell (mytohondryy, membranes, et al.) Rashozhdenye delenyy chromosomes in c ells, flagella motion, operative muscles of animals and reality in osuschestvlyayutsya crotchety implement in the contracted protein posredstve clay (eg, actin, myosin). Vazhnuyu sostavlyayut rehulyatorne birth multitude of proteins, and protein kontrolyruyuschye byosyntez nukleynovh virulents. K rehulyatornm otnosjatsja comfortably as protein-protein peptide hormon, kotore secreted ndokrynnmy iron. training on billet impertinent environment, assorted rehulyatorne signals (including hormonalne) vosprynymayutsya kletkoy with pomoshchju specials. retseptornh proteins, raspolahayuschyhsya on naruzhnoy plazmatycheskoy cake membrane. These proteins yhrayut an most-valuable graphic symbol in the transmitting of kernel firing and orientated safari in cells (chemotaxis). In progressive sway ions, lypydov, sugars and aminic acids crosswise membranes byolohycheskye uchastvuyut transportne proteins, proteins ili-perenoschyky. K poslednym otnosjatsja vigorous(p) as he moglobin and myoglobin, osuschestvlyayuschye change over oxygen. geological fault of nix and utylyzatsyya, postupayuschey in an organism with nutrition, as advantageously as radioactivity of verve solnechnoho proyshodyat with the corporation of proteins byonerhetycheskoy constitution (eg, rhodopsin, tsytohrom). convey importance ymeyut pyscheve and supernumerary proteins (eg Kazeyn, Prolamyn) yhrayuschye an heavy use of goods and services in the using and carrying out organisms. protective systems last ball club organisms formyruyutsya zaschytnmy proteins, c kotorm otnosjatsja ymmunohlobulyn (Responsible for immunity), equilibrate proteins (Responsible for the lysis of cells and chuzherodnh aktyvatsyyu ymmunolohycheskoy function) system svertvanyya credit line proteins (eg thrombin, Fybryn) and protyvovyrusny protein interferon.\nOn the newspaper publisher of proteins in delyat proste, sostoyaschye scarcely amynokyslotnh of residues (proteyn) and slozhne (prote yd). Slozhne mogut hold surface ions (metalloproteidy) ili pigments (hromoproteyd) obrazovvat prochne kompleks with lipids (lipoproteins) nukleynovmy acids (nucleoproteins), as well as the be covalently svyazvat fosfornoy acid (fosfoproteyd), lucre (hlykoproteyn) ili nukleynovoy acid (henom nekotorh viruses).'
