How do anomers differ from epimers?

Expert Answer:

Carbohydrates which differ in configuration at the glycosidic carbon (i.e. C1 in aldoses and C2 in ketoses) are called anomers. The carbohydrates which differ in configuration of any asymmetric carbon atom other than glycosidic carbon is called epimer. For example, α-D- glucose and β-D- glucose are anomers (differ at C1; glycosidic carbon). On the other hand, glucose and mannose are epimers (differ in configuration at C2).
