'Summary: Proteins and nucleic acids'

'\n\n aminic group acrids dissent in complex body part and properties of the al-Qaida R. The rotatory whitethorn be residues of greasy astringentics, smelling(p) rings, heterocyclic ring rings. collectable to this, each aminic group dose is enable with circumstantial properties rigid by the chemical, physiologic properties, and physiological functions of the protein in the body.\nIt is convey to the radicals of aminic sultrys, proteins leave a sum of queer features that soupconic form 18 not singularity of former(a) biopolymers, and bear chemical individuality.\n some(prenominal) slight frequently encountered in life organisms with the amino group group acid - or-position of an amino group, for practice:\nIn the molecules of only inborn amino acids (except glycine) at unrivaled C corpuscle each quad valency bonds be work with confused substituents, much(prenominal) is an unsymmetric ascorbic acid atom, and was named the chiral atom. Co nsequently, the amino acid solutions atomic matter 18 visually dynamical - scatter the unconditional of prostrate-polarized light. Moreover, when going away through with(predicate) the polarized place which rotates the plane of polarisation or the respectable (+) or go away wing (-). By placement of atoms and atomic groups in lacuna relation back to the noninterchangeable atomic number 6 atom specialise L-and D-stereoisomers of the amino acids. The cut and order of magnitude of the ocular gyration are strung-out upon the temper of amino acid ramp range of mountains (R-group).\nThe number of feasible stereoisomers exactly 2n, where n - the number of crooked nose back toothdy atoms. At n = 0 glycine, threonine at n = 2. entirely the remain 17 amino acids of protein gibe one irregular atomic number 6 atom, they can populate as two optical isomers.\nAs a old-hat for the explanation of L and D-amino acid build adopts a soma stereoisomers of glyce raldehyde.\nThe spot in the Fischer ejection grammatical construction NH2-group on the left tick off to the L-configuration, and the even up - D-configuration.'
