Chapter 25, Problem 97AP

Interpretation Introduction

Interpretation:

In the $\alpha \text{-amino}$ acids, the presence of “R” that belongs to the ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}$ alkyl group is to be identified.

Concept Introduction:

Amino acids are basic units of proteins.

A large molecule consists of one or more amino acids chain in a specific order is known as a protein.

Amino acids are organic compounds containing amine and carboxyl functional groups. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen.

Isomeric ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}$ alkyl group has four different structural formulae, but the molecular formula would be the same.
