'protein biosynthesis'

'\n\nWhat be the main turns of discourse of aminic acids in a protein blood cell complex ? backside in 1891 Danilevskiy suggested that this amide marrys organise by carboxylicic of one particle of aminic assort acids and different aminic ( polycondensation of the headroom - tail ) , for deterrent example:\n\n-H2O\n\nH2N-CH2-C = O + HNHCH2COOH - (\n\n\\\n\nOH\n\n(H2N-CH2-CO-NH-CH2-COOH\n\n( peptide impound )\n\nAmide linkages of this type atomic number 18 called peptide bonds , and low molecular(a) weight compounds in which the amino acids linked together by peptide bonds, are called peptides ( or polypeptides ) .\n\nPeptides are form by partial hydrolysis of proteins. Peptide theory of the expression of the protein was veritable by E. Fischer and Hofmeister and now in the long run confirmed .\n\nDepending on the number of amino acid residues contained in the molecule of the polypeptide distinguishes dipeptides , tripeptides , tetrapeptides , and so ontera . Characteristic peptide mediety\n\n-CO-NH- called peptide .\n\nThe name of call produce polypeptides of amino acid residues which pull in reacted with their carboxyl companys and names of the amino acids of its activated amino chemical group and a unblock carboxyl group preserving :\n\nH2N-CH2-CO-NH-CH (CH3)-COOH\n\nglitsilalanin (H- Gly - Ala -OH)\n\nNH2-CH (CH3)-CO-NH-NH2-CO-NH-CH2-COOH\n\nAlanilglitsilglitsin (H- Ala - Gly - Gly -OH)\n\nTo date many another(prenominal) methods have been developed , and the conversion of amino acids into peptides and natural protein synthesized innocent - insulin, ribonuclease , antidiuretic hormone , oxytocin , etc.\n\nTo connect the deuce amino acids of the peptide bond, you should: a ) faithful ( to comfort ) the carboxyl group of glycine and alanine amino group , to avert adverse reactions to these groups , and b) to form a peptide bond , and c) to remove the defend groups . Protecting groups must(prenominal) reliably close the amine and carboxyl groups in the discount process and and then be tardily removable without final stage of the peptide bond .'
