Anomers are cyclic monosaccharides or glycosides that are epimers, differing from each other in the configuration of C-1 if they are aldoses or in the configuration at C-2 if they are ketoses. The epimeric carbon in anomers are known as anomeric carbon or anomeric centre.
An anomer is actually an epimer (also a cyclic saccharide) which differs in configuration, particularly at the acetal or hemiacetal carbon (refer to the image below to differentiate between acetal and hemiacetal carbons).
- An anomer is a kind of stereoisomer.
- The anomers are saccharides or glycosides that are epimers, which are distinct from each other in the configuration at C-2.
- If they are ketoses, or in the configuration of C-1, if they are aldoses.
