Chapter 21, Problem 60E

Interpretation Introduction

Interpretation: The amino acid on a protein strand forms a hydrogen bond with another amino acid if four amino acid units away. The next amino acid on the chain does the same hydrogen itself over a significant part of the protein chain. The resulting pattern in the protein is an example of each kind of structure (primary, secondary, tertiary, or quaternary)?

Concept Introduction:

An amino acid on a protein strand forms a hydrogen bond with another amino acid that is four amino acid units away. The next amino acid on the chain does the same, hydrogen bonding to an amino acid that is four amino acids away from it.
