Chapter 20, Problem 2CE

Interpretation Introduction

Interpretation:

Whether the protein structure in the form of the helix of amino acids in a spiral protein chain corresponds to primary, secondary, or tertiary structure of a protein molecule is to be stated.

Concept introduction:

Primary structure of a protein consists of a long chain comprised of thousands of amino acids. Secondary structure of a protein consists of around ten amino acids in the bend and twisted form, known as $\text{α-helix}$ structure. Tertiary structure of a protein consists of a three dimensional $\text{α-helix}$ structure.
