Question

Quizplus · Accepted Answer

Denaturation of a protein usually involves breaking the non-covalent bonds that maintain the protein's tertiary and quaternary structures. This leads to a loss of the protein's functional properties, and the secondary structure may also be affected. However, the primary structure (amino acid sequence) remains intact.
