Which factor would NOT denature a protein?
- 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.
