Chapter 26, Problem 26.22YT

Interpretation Introduction

Interpretation:

All of the peptide linkages in the hexapeptide in Figure 26-44 are to be identified, and how many are there is to be told.

Concept introduction:

A protein is characterized by its primary structure; different proteins have different primary structures. The amide functional group is responsible for connecting adjacent amino acids along a protein’s main chain, and each of those amide groups is called a peptide linkage or peptide bond. In the hexapeptide in Figure 26-44, the primary sequence is Phe-Cys-Thr-Gln-Ala-Ala.
