Question

what are anomers explain the existence of an anomer in sugar taking d_ glucose as an illustrative case​

Answer 1

Explanation:

When a sugar molecule, for example, D-glucose converts into cyclic form a new chiral center is generated at C-1. This carbon which generates a chiral center is called anomeric carbon. So at anomeric carbon, the configuration of the OH atom can be different forming different forms which are called anomers.

Answer 2

Answer:

Anomer are designated α if the configuration at the anomeric carbon is the same as that at the reference asymmetric carbon in a Fischer projection. If the configuration differs the anomer is designated β. For example, α-D-glucopyranose and β-D-glucopyranose, the two cyclic forms of glucose, are anomers.
