Which one of the following is not affected by protein denaturation? A. Primary structure B. Tertiary structure C. Secondary structure D. Disulfide bonds E. Quaternary structure
Understand the Problem
The question is asking about the different structures of proteins and which one is not affected during the process of protein denaturation. This involves understanding the definitions and characteristics of primary, secondary, tertiary, quaternary structures, and disulfide bonds.
Answer
Primary structure
The primary structure of a protein is not affected by denaturation.
Answer for screen readers
The primary structure of a protein is not affected by denaturation.
More Information
Denaturation affects the secondary, tertiary, and quaternary structures of proteins by disrupting non-covalent interactions. However, the primary structure, which consists of the amino acid sequence linked by covalent peptide bonds, remains intact.
Tips
A common mistake is assuming all structural levels are disrupted during denaturation, but primary structure remains unchanged.
