Which is the correct structure for $\alpha$-D-glucopyranose?

Question

Quizplus · Accepted Answer

The correct structure for F1F1F1S1F1F1F10-D-glucopyranose is a representation of the monosaccharide glucose with modifications at positions 1, 3, and 6. The structure can be easily recognized as an alpha-linked glucose molecule with three substituents at positions 1, 3, and 6. The correct representation of this structure is shown in III, which has an alpha-configuration at the anomeric position and modifications at positions 1, 3, and 6. The other structures (I, II, and IV) do not accurately represent the modifications present in F1F1F1S1F1F1F10-D-glucopyranose.
