α and β-glucose differ in the orientation of -OH group around:
Correct answer: C. C1
- A. C3
- B. C5
- C. C1
- D. C2
Explanation
The correct answer is C1 because α and β-glucose differ in the orientation of the hydroxyl (-OH) group at the anomeric carbon, which is C1. In α-glucose, the -OH group on C1 is positioned on the opposite side of the ring compared to the CH2OH group, while in β-glucose, it is on the same side. The other carbon positions (C2, C3, and C5) do not affect the anomeric nature of glucose, thus these options are incorrect.

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.
