Original Khojo Papers practice question — not from a past board paper.
Denaturation is the loss of the biological activity of a protein caused by heat, a change of pH, or certain chemicals. The secondary and tertiary structures are destroyed as the hydrogen bonds and other weak interactions that hold the chain in its shape are broken, while the primary structure, the sequence of amino acids, remains intact.
