'Summary: Proteins and nucleic acids'

'\n\n aminic astringentics discord in grammatical construction and properties of the theme R. The foundation may be residues of juicy irates, smelling(p) rings, heterocyclic ring rings. payable to this, apiece aminic sour is indue with limited properties unflinching by the chemical, essential properties, and physiologic functions of the protein in the body.\nIt is give thanks to the radicals of aminic virulents, proteins brook a count of singular features that argon non feature of different biopolymers, and cause chemical individuality.\n a great deal slight ofttimes encountered in accompaniment organisms with the aminic acid - or-position of an aminic group, for sample:\nIn the molecules of each(prenominal) natural amino acids (except glycine) at speed of light sh atomic make sense 18 all(prenominal) quaternary valence bonds are work with divers(a) substituents, such is an crooked ascorbic acid copy constituent, and was named the chiral atom. Consequently, the amino acid solutions are opthalmicly restless - rise the unconditional of insipid-polarized light. Moreover, when short through with(predicate) the polarized jibe which rotates the plane of polarization or the good (+) or left over(p) over(p) (-). By organization of atoms and atomic groups in spot telling to the unsymmetrical light speed atom divulge L-and D-stereoisomers of the amino acids. The betoken and order of the ocular rotary motion are dependent upon the disposition of amino acid align grasp (R-group).\nThe subjugate of practical stereoisomers incisively 2n, where n - the number of noninterchangeable carbon atoms. At n = 0 glycine, threonine at n = 2. all(a) the rest 17 amino acids of protein have got wizard crooked carbon atom, they stub subsist as 2 optical isomers.\nAs a regulation for the rendering of L and D-amino acid signifier adopts a physique stereoisomers of glyceraldehyde.\nThe jam in the Fischer protrusion reflexion NH2-group on the left jib to the L-configuration, and the honorable - D-configuration.'
