Question

The tertiary structure of a typical globular protein is established by the complex folding of its polypeptide chains. Which of the following intermolecular forces does NOT actively contribute to stabilizing this specific 3D structure?

Answer: C

💡 Solution & Explanation

The tertiary structure of proteins is stabilized by hydrogen bonds, disulfide ($-S-S-$) bridges, ionic bonds (salt bridges), van der Waals forces, and hydrophobic interactions. Phosphodiester bonds form the primary backbone of nucleic acids (DNA/RNA), not proteins.
