Q. Assertion : The two cyclic hemiacetal forms of glucose, $\alpha$-form and $\beta$-form are called anomers.
Reason : Anomers differ only in the configuration of the hydroxyl group at $C-1$.

Biomolecules

Solution:

The two cyclic hemiacetal forms of glucose differ only in the configuration of hydroxyl group at $C−1$, called anomeric carbon (the aldehyde carbon before cyclisation). Such isomers, i.e., $α$ & $β$ form are called anomers.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
