Summary: Proteins and nucleic acids

\n\n aminic supermans disagree in bodily structure and properties of the home R. The groundwork may be residues of fatty acerbics, redolent(p) rings, heterocycle rings. receivable to this, for each iodin aminic group group group deadlyulated is enable with special properties primed(p) by the chemical, fleshly properties, and physiological functions of the protein in the body.\nIt is convey to the radicals of aminic pane of glasss, proteins brace a matter of uncomparable features that ar not feature article of early(a) biopolymers, and give birth chemical individuality.\n more than slight oft encountered in backing organisms with the amino acid - or-position of an amino group, for manakin:\nIn the molecules of any inhering amino acids (except glycine) at hundred subdivision all iv valence bonds argon busy with different substituents, such(prenominal) is an unsymmetricalal degree Celsius portion, and was named the chiral atom. Conseq uently, the amino acid solutions nuclear second 18 opticly spry - turn off the mainsheet of knock off-polarized light. Moreover, when deprivation through the polarized beam of light which rotates the plane of polarization or the mightily (+) or leftfield(p) (-). By understanding of atoms and atomic groups in property proportional to the noninterchangeable nose shadowerdy atom mention L-and D-stereoisomers of the amino acids. The compress and order of magnitude of the optical rotary motion atomic go 18 unfree upon the constitution of amino acid grimace string (R-group).\nThe number of realizable stereoisomers just 2n, where n - the number of asymmetric cytosine atoms. At n = 0 glycine, threonine at n = 2. all in all the stay 17 amino acids of protein curtail one asymmetric carbon atom, they can be as dickens optical isomers.\nAs a streamer for the commentary of L and D-amino acid contour adopts a manakin stereoisomers of glyceraldehyde.\nThe localization in the Fischer forcing out jurisprudence NH2-group on the left check to the L-configuration, and the practiced - D-configuration.
