Solution

Correct Answer:

Secondary/tertiary/quaternary structures (non-covalent)

  1. Folded State: Natural proteins are in a specific 3D shape called the 'native conformation'.
  2. Denaturation: A process where a protein loses its biological activity due to physical or chemical changes (high temp, pH change).
  3. What breaks: It disrupts the relatively weak non-covalent interactions (Hydrogen bonds, hydrophobic interactions, salt bridges) and sometimes disulfide bonds.
  4. What remains: The primary structure (linear sequence of amino acids held by covalent peptide bonds) is usually unaffected.
  5. Result: The protein becomes 'uncoiled' and loses its functional shape.

This easy difficulty chemistry question is from the chapter biomolecules, covering the topic of denaturation. It appeared in the 2025 exam.
