Which factor would NOT denature a protein?
Correct answer: D. Dissolving it in pure water at room temperature
- A. Boiling
- B. Strong acid
- C. Heavy metal ions
- D. Dissolving it in pure water at room temperature
Explanation
Many proteins dissolve in water without any loss of structure, since water is the medium they normally function in. Heat, extremes of pH, heavy metals, alcohol and vigorous agitation all disrupt the weak interactions holding the fold. Denaturation destroys function while leaving the peptide backbone intact.

About Importance of Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their biological roles depend on primary, secondary, tertiary and quaternary structure. Coverage includes enzymes, hormones, antibodies, transport proteins, muscle fibres and structural tissues, together with denaturation and the effects of heat, pH and chemicals.
