Question

When a biologically active globular protein is subjected to extreme physical stress such as boiling water, it rapidly undergoes coagulation. At a molecular level, what exact structural degradation is definitively responsible for this irreversible phenomenon?

Prashant Kotian · Accepted Answer

Correct answer: C. Denaturation involves changes in temperature or pH that violently disrupt weak stabilizing forces (hydrogen bonds, hydrophobic interactions) leading to the complete loss of 2° and 3° structures. The strong covalent peptide bonds dictating the 1° primary sequence remain entirely unbroken.
