Chapter 21, Problem 15A

Interpretation Introduction

Interpretation:

The tertiary structure of a protein must be explained. Also, the difference in secondary and tertiary structures needs to be explained.

Concept Introduction:

Secondary structure of a protein gives the idea whether the protein has beta sheet structure or α-helix structure.

Tertiary structure represents the overall structure of the protein.

Answer to Problem 15A

Tertiary structure of the protein describes whether the protein is long, narrow or globular.

Secondary structure of a protein represents the arrangement of the protein molecule in space.

Explanation of Solution

In tertiary structure, the secondary structure is also present. Protein twists and takes proper turn to maintain the overall structure.

For example if a protein is globular then keeping the secondary structure intact the protein will bend accordingly so that globular structure is attained.
