Biomolecules · Class 12 · JEE Main Previous Year Question
Coagulation of egg, on heating is because of:
- a✓
Denaturation of protein occurs
- b
The secondary structure of protein remains unchanged
- c
Breaking of the peptide linkage in the primary
- d
Biological property of protein remains unchanged
Denaturation of protein occurs
Step 1: Understanding Egg Coagulation — Heating an egg causes its proteins to unfold in a process called denaturation.
Step 2: Molecular Changes — This thermal treatment breaks the weak intermolecular forces that maintain the higher-order structures (secondary, tertiary, quaternary).
Step 3: Final Result — As these structures are lost, the protein molecules aggregate and form an insoluble white solid. Correct option is (a).
Remember: Denaturation destroys biological function but leaves the primary structure (amino acid sequence) unchanged.
