Chapter 18, Problem 18.65QP

Interpretation Introduction

Interpretation:

The rigidity in structure of protein because of peptide bond has to be explained.

Concept Introduction:

The peptide bond is an amide bond between $-{\text{COO}}^{-}$ of one amino acid and ${\text{α-NH}}_{\text{3}}^{\text{+}}$ group of another amino acid. Two amino acids units are bonded to each other by a peptide $\left(-\text{CO}-{\text{NH}}_{\text{2}}-\right)$ bond in the protein molecule. The peptide bond is formed from the condensation reaction of two amino acids.
