Chapter 18.5, Problem 18.19P

Interpretation Introduction

Interpretation:

Peptide bond in vasopressin 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 $(-COOH)$ and a $R$ group is considered as side chain, when all these are bonded to same carbon atom.

In protein the amide bond can link together with two amino acids to form a peptide bond.

Link formation results from the release of water.
