Chapter 22, Problem 2E

Interpretation Introduction

Interpretation:

The way amino acids are subdivided by the nature of their R groups is to be stated.

Concept introduction:

The amino acids are the building blocks of protein molecules. The amino acid contains one amino group $\left(-{\text{NH}}_{\text{2}}\right)$, a carboxylic acid group $\left(-\text{COOH}\right)$ and $-\text{R}$ (side chain). When proteins are broken down, amino acids are produced.
