In fibrous proteins, polypeptide chains are held together by
Correct answer: C. Hydrogen bonds
- A. Van der Waals forces
- B. Electrostatic forces of attraction
- C. Hydrogen bonds
- D. Covalent bonds
Explanation
This is the correct answer. Fibrous proteins often have secondary structures stabilised by hydrogen bonds. These bonds form between the hydrogen atom of one amino acid and the oxygen or nitrogen atom of another amino acid. Therefore, the correct answer is option C: "Hydrogen bonds," as they play a significant role in holding polypeptide chains together in fibrous proteins.

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.
