Two sugars that differ in configuration at only one chiral center are described as epimers.

d-mannose and d-talose are epimers and d-glucose and d-mannose are epimers, whereas d-glucose and d-talose are not epimers but merely diastereomers

When the anomeric hydroxyl of a D-hexose is on the same side of the ring as C-6, the structure is β a by definition; when it is on the opposite side from C-6, the structure is α.

The two diastereomers of glucose in its "pyranose" form are called the alpha (a) and beta (B) isomers, which differ in the orientation of the OH at C-1
