At neutral p H , amino acid that has net positive, net negative and neutral is to be identified. 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. Zwitter ion has both positive as well as negative charge, thus it is also called neutral dipolar ion. Zwitter ion accepts proton in acidic condition and in basic condition zwitter ion lose electrons.

Specific rotation is a measure of a solution's capacity to rotate circularly polarized light. The unfolding of the a helix of a polypeptide to a random conformation is accompanied by a large decrease in specific rotation. Polyglutamate, a polypeptide made up of only 1-Glu residues, has the a helix conformation at pH 3. When researchers raise the pH to 7, there is a large decrease in the specific rotation of the solution. Similarly, polylysine (1.-Lys residues) is an a helix at pH 10, but when researchers lower the pH to 7 the specific rotation also decreases, as shown in the graph. a Helix Specific rotation Poly(Glu) a Helix Random conformation Poly(Lys) Random conformation T + ° 2 4 6 В 10 12 14 PH Complete the statements about the molecular mechanism for these changes in specific rotation.
