Chapter 22, Problem 22.36P

Interpretation Introduction

Interpretation:

The acidic amino acids should be identified.

Concept Introduction:

Amino acids are defined as species with both amino $-{\text{NH}}_{\text{2}}$ and carboxylic $-\text{COOH}$ groups. They can be classified as acidic, basic and neutral depending upon their side chain and nature in neutral pH.

An amino acid, with one or more amino group in the side chain is basic in nature due to proton acceptor tendency of amino group.

Similarly, amino acids with one or more carboxyl groups in side chains are acidic in nature.
