The most stable tertiary configuration is due to:
Correct answer: C. Disulfide bonds
- A. Ionic bonds
- B. Hydrogen bonds
- C. Disulfide bonds
- D. Hydrophobic interactions
Explanation
The most stable tertiary configuration in proteins is primarily due to disulfide bonds. These covalent bonds form between sulfur atoms in cysteine residues, providing a strong and stable link in the protein's structure, superior to non-covalent interactions like ionic bonds, hydrogen bonds, and hydrophobic interactions. While these other interactions all contribute to the protein's overall architecture, disulfide bonds are the most effective in maintaining stability under varied conditions.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
