Chapter 21, Problem 83E

(a)

Interpretation Introduction

Interpretation: The amino acids containing the given functional groups in their R group are to be determined.

Concept introduction: Amino acids are defined as organic compounds which contain amine $\left({\text{-NH}}_{\text{2}}\right)$ and carboxyl $\left(\text{-COOH}\right)$ functional groups, along with a side chain (R group) attached to each amino acid. They are the building blocks of proteins and have the backbone structure, in which they contain, a carboxyl group, $\text{α}$ hydrogen and a variety of functional groups attached to the $\text{α}$ carbon.

To determine: The amino acids containing the alcoholic functional group.
