Chapter 9, Problem 9.13EP

(a)

Interpretation Introduction

Interpretation: The classification of the given standard amino acid as nonpolar, polar neutral, polar acidic, polar basic has to be stated.

Concept introduction: Amino acid is a compound that is composed of ${\text{NH}}_{\text{2}}$ (amino) group and $\text{COOH}$ (carboxylic acid) group.  The amino acids that are present in proteins are called standard amino acids.  The standard amino acids are classified as nonpolar, polar neutral, polar acidic and polar basic amino acids.
