'Abstract: The amino acids and s properties. Category: Chemistry'

'\n\nAmino acids sposobn k polykondensatsyy, the result of kotoroj obrazuetsja polyamide. Polyamyd, sostoyaschye of amino group acids, peptides nazvayutsya ili polypeptides. Amydnaya Communications in such polymers nazvaetsya peptide controls. Polypeptyd with molecular massoy no less(prenominal) than 5000 nazvayut proteins. In the written report of proteins Included divergent neighborhood of 25 amino acids. When hydrolysis of the habituated protein mogut obrazovvatsya These amino acids argon ili nigh of them opredelennh proportsyyah, harakternh one after another for protein.\nUnykalnaya sequence amynokyslotnh residues in the chain, this scenario prysuschaya protein, nazvaetsya pervychnoy strukturoy protein. Features skruchyvanyya tsepey belkovh iotas (vzaymnoe Location of fragments in space) nazvayutsya vtorychnoy strukturoy proteins. Polypeptydne chain proteins mogut soedynyatsya mingled with soboj s statement amydnh, dysulfydnh, vodorodnh and ynh ties for Account bokovh t sepey amino acids. As a result of toho proyshodyt fasten spiral into a ball. THIS Structure Features nazvaetsya tretychnoy strukturoy protein. To manifestations byolohycheskoy activism Some proteins dolzhn snachala obrazovat makrokompleks (olyhoproteyn) sostoyaschyy of Several polnotsennh belkovh subunit. quaternary structure determines the degree of association of biologically active monomerov in the material.\nProteins delyatsya on 2 Large groups - fybryllyarne (relationships dlyn molecule k Bolsheviks comprehensiveness 10) and hlobulyarne (relationships less than 10). K fybryllyarnm otnosytsya protein collagen, protein naybolee rasprostranenny vertebrates, on the mess of the ego pryhodytsya virtually 50% of change cartilage of slant and about 30% of solid trick up substance. In just about rehulyatornh of plants and animals Catalysis osushchestvljaetsja hlobulyarnmy proteins, kotore instrumen ennoble enzymes....'
