Interpretation Introduction

Interpretation:

The reason as to why two $K_{\text{a}}$ values obtained for alanine is to be explained. The functional groups represented by these values are to be stated. The number of $K_{\text{a}}$ values obtained for glutamate is to be stated.

Concept introduction:

The structure of proteins has four stages. These four stages are: primary, secondary, tertiary and quaternary structures. In primary structure, the amino acids are arranged to give the backbone of protein. In secondary structure, the pattern of the peptide chain is arranged in certain order. In tertiary structure, the interactions between the side chains of amino acids are considered. In quaternary structure, two or more peptide chains are linked.
