Chapter 20, Problem 53RQE

Interpretation Introduction

Interpretation:

The N-terminal and C-terminal of polypeptide Tyr-Gly-His-Phe-Val has to be identified.

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.  The peptides are named considering the amino acids present in it.  Peptides are named simply as acyl derivatives of the amino acid present in C-terminal.
