Answer» Solution :(i) Peptide linakge: Amino acidsare bifunctionalmoleculeswith `NH_(2)` GROUP at its oneend andCOOH at the other . Therforethe COOH of onemolecules and`NH_(2)`of anothermolecule caninteract witheliminationof a `H_(2)O`molecule to from an amide like linkagecalledpeptidebondor peptidelinkage . (ii) Primarystrcuture: Thesequencein whichamino acids are linked togetherin a polypeptidechain froms theprimary STRUCTURE. (iii) DENATURATION: The process of by whichsecondaryand tertiarystructure of PROTEINS getdisturbed by CHANGEOF pH or temperature ,so that theyarenot ableto perform theirfucntions, is calleddenaturationof proteins. |
