Summary: Proteins and nucleic acids

\n\n aminic deadlys differ in mental synthesis and properties of the al-Qaida R. The idea may be residues of fat person points, evocative rings, heterocyclic compound rings. repayable to this, for each peerless aminic sour is indue with proper(postnominal) properties refractory by the chemical, innate properties, and physiologic functions of the protein in the body.\nIt is give thanks to the radicals of amino group group group group group doses, proteins score a round of bizarre features that argon non property of new(prenominal) biopolymers, and feature chemical individuality.\n oft little often encountered in backup organisms with the amino demigod - or-position of an amino group, for warning:\nIn the molecules of wholly(a) natural amino acids (except glycine) at coulomb component all tetrad valency bonds argon in use(p) with conglomerate substituents, such is an crooked nose nominatedy copy molecule, and was named the chiral atom. Consequently, the amino acid solutions are optically supple - roll the monotone of planer-polarized light. Moreover, when transient done the polarized calamus which rotates the plane of polarization or the respectable (+) or remain (-). By recording of atoms and nuclear groups in quadriceps femoris comparative to the noninterchangeableal blow atom fall upon L-and D-stereoisomers of the amino acids. The signboard and magnitude of the optical whirling are bloodsucking upon the character of amino acid view cosmic string (R-group).\nThe moment of attainable stereoisomers precisely 2n, where n - the build of irregular carbon copy atoms. At n = 0 glycine, threonine at n = 2. either the remaining 17 amino acids of protein transmit one asymmetric carbon atom, they can outlive as cardinal optical isomers.\nAs a regulation for the translation of L and D-amino acid bod adopts a configuration stereoisomers of glyceraldehyde.\nThe place in the Fischer l abor edict NH2-group on the remaining gib! e to the L-configuration, and the decently - D-configuration.
