Chapter 21, Problem 87E

Interpretation Introduction

Interpretation: The structures of $\text{dipeptides}$ of serine and $\text{alanine}$ are to be drawn.

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. Dipeptide is formed when two amino acid residues are joined through peptide bond with an elimination of water molecule.

To determine: The structures of $\text{dipeptides}$ of serine and $\text{alanine}$.
