Biomolecules

-D-glucose and -D-glucose are

1. epimers
2. anomers
3. enantiomers
4. diastereomers

Answer

(2) anomers

Solution

α-D-glucose and β-D-glucose are the two cyclic (pyranose) forms of D-glucose; they differ only in the configuration of the –OH group at C1, the anomeric (hemiacetal) carbon.

∵ As per NCERT, such isomers, i.e. the α-form and the β-form, are called anomers.
