The given tripeptide at low p H and at high p H structures has to be drawn. Concept Introduction: Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins. Amino functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R group is considered as side chain, when all these are bonded to same carbon atom. Zwitterion has both positive as well as negative charge, thus it is also called neutral dipolar ion. Zwitterion accepts proton in acidic condition and in basic condition zwitterion lose electrons. At low p H , amine and carboxylic acid are protonated and at high p H amine and carboxylic acid are deprotonated.
