Chapter 22, Problem 89E

 (a)

Interpretation Introduction

Interpretation: The sequences of all possible tetra peptides of the given amino acids are to be determined.

Concept introduction: When two or more amino acids are linked in a chain, a compound called peptide is formed in which the carboxyl group of each acid is joined to the amino group of the next forming a $\text{-OC-NH-}$ bond, known as peptide bond. A tetra peptide is defined as an $\text{oligopeptide}$ as it is formed by joining four amino acids by peptide linkage.

To determine: The sequences of all possible tetra peptides of the given amino acids.
