`alpha-D` glucose and `beta-D`-glucose differ from each other due to the difference in one of the carbon atoms, with respect to its.

Options

A. conformation
B. configuration
C. number of OH-groups
D. size of hemiaetal ring

Answer

B

Explanation

The isomer having the hydroxyl group (-OH) on the right is called `alpha-`D-glucose and one having the hydroxyl group (-OH) on the left is called `beta-`D-glucose. Such pairs of optical isomers which differ in the configuration only around `C_(1)` atom are called anomers. thus `alpha`-D-glucose and `beta-`D-glucose are anomers.
