Differentiate between anomers and epimers.

Explanation

Anomers are the carbohydrates which differ in configuration at the glycosidic carbon, i.e., `C_1` in aldoses and `C_2` in ketoses. For example, `alpha`-D-glucose and `beta`-D-glucose are anomers.
Epimers are the carbohydrates which differ in configuration at any other carbon other than glycosidic carbon. For example, glucose and mannose are epimers
