Question

$\alpha$-D-glucose differs from $\beta$-D-glucose due to difference in one of the carbon atoms with respect to its:

• A. number of $-OH$ groups
• B. configuration
• C. conformation
• D. size of hemiacetal ring

Answer 1

The correct option is B configuration

$\alpha$ glucose and $\beta$ glucose are structurally identical except with the difference in the "configuration" of the anomeric carbon atom. So, they are also called as anomers.
