The pyranose form of glucose dominates (>99%) at equilibrium in aqueous solution
#Id: 7847
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
#Id: 7846
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.

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
