WebAnd if these diastereomers are cyclic hemiacetals like sugars are, then they are classified as anomers. Therefore, D and L Glucose are enantiomers, while ɑ-D-glucose and β-D-glucose are diastereomers. To summarize what we learned about epimers and anomers. Epimers are diastereomers that differ in the configuration of only one chiral center.
