Which type of bonds is required to maintain the alpha helix configuration of a protein?
Correct answer: C. Hydrogen bonds
- A. Hydrophobic interactions
- B. Disulfide bonds
- C. Hydrogen bonds
- D. Ionic bonds
Explanation
Hydrogen bonds are the primary type of bonds required to maintain the alpha helix configuration of a protein. In an alpha helix, the backbone of the polypeptide chain forms a helical structure stabilized by hydrogen bonds between the carbonyl oxygen atom of one amino acid and the amide hydrogen atom of another amino acid, typically four residues away in the sequence. These hydrogen bonds create a stable and regular helical conformation.

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.
