Chapter 21, Problem 2STP
Interpretation Introduction

Interpretation: A pleated sheet, structure of proteins needs to be identified.

Concept Introduction:

Protein − proteins are composed of the different types of amino acids and they are bonded together with the help of the peptide bonds.

Based on the arrangement of the amino acids proteins classified into four structures, such as primary, secondary, tertiary and quaternary structure.

Expert Solution & Answer
Check Mark

Answer to Problem 2STP

Correct answer: Option (B) the secondary structure of a protein.

Explanation of Solution

Reason for correct option:

The secondary structure of proteins is consists of the beta strands. It is complex form of proteins, it beta strand are formed with hydrogen bond, the twisted bond converted into a sheet that is termed as pleated sheet

Conclusion

Reasons for incorrect options:

Option (A) the primary structure of proteins is not the present in the sheet form of the amino acids, hence it is the incorrect option.

Option (C) the tertiary structure of proteins is not the arranged in the pleated sheet of the amino acids, hence it is the incorrect option.

Option (D) disulfide is not the sheet form of the amino acids, hence it is the incorrect option.
