Chapter 21.4, Problem 21.6PP

Interpretation Introduction

Interpretation:

The peptide bond should be located in the dipeptide of the given ball-and-stick model, also the amino acids that form the dipeptide and the name of the dipeptide using three-letter abbreviations for the amino acids should be determined.

Concept introduction:

Ball-and-stick model is the three dimensional description of molecules. In this model atoms are represented by spheres, and connected bonds are represented by rods.

Functional group is a group of atoms and bonds that has a predictable chemical behavior. The similar functional group undergoes similar reactions.
