For the given Glycine molecule structural formula has to be written for its zwitterion form. 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 (alkyl) group is considered as side chain, all these are bonded to same carbon atom. Zwitterion has both positive as well as negative charge, it is also called neutral dipolar ion. Zwitterion accepts proton in acidic condition and in basic condition zwitterion lose its proton. At low p H , amine and carboxylic acid are protonated and at high p H amine and carboxylic acid are deprotonated.
