During denaturation of proteins which structure of proteins remain intact?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Primary Structure
- Denaturation of proteins involves the disruption of secondary, tertiary, and quaternary structures due to:
- Heat
- pH changes
- Organic solvents
- Detergents
- Primary structure, which is the sequence of amino acids linked by peptide bonds, remains intact because peptide bonds are not broken during denaturation.
Hence, the structure that remains intact is Primary Structure.
