One of the common secondary structure of protein is:
Correct answer: A. α-helix
- A. α-helix
- B. β-helix
- C. γ helix
- D. Pi helix
Explanation
The α-helix is one of the most common secondary structures in proteins, known for its stability and regularity, due to hydrogen bonding between every fourth amino acid. This structure is found in many functional proteins. In contrast, the β-helix is not a secondary structure; it is a type of tertiary structure. The γ helix and Pi helix are rare and less stable helical forms, making them less prevalent in the secondary structures of 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.
