Chapter 20, Problem 48RQE

Interpretation Introduction

Interpretation:

All possible tripeptides that can be obtained which contains one unit of glycine, phenylalanine, and leucine has to be written.

Concept Introduction:

Amino acids are compounds that contain an amino group and carboxyl group in it.  The carboxyl carbon atom is the $\text{C}-1$ carbon atom.  Amino acids combine together by condensation reaction resulting in formation of a peptide linkage.  If two amino acids combine to form a peptide linkage, the formed compound is known as dipeptide.  Peptide linkage $\left(\text{CO}-\text{NH}\right)$ is formed by a loss of water molecule.  If three amino acids are condensed, then a tripeptide is formed which has two peptide linkage.
