How many different glycosides can be formed by linking one D-glucopyranose and one D-galactopyranose? Explain your reasoning.
Solution:
There are 19 possible disaccharides [glycosides] of D-glucopyranose and 19 glycosides of D-galactopyranose as both of them are exist in α and β forms. The glycosidic bond can be formed between the anomeric hydroxyl group on one glucose unit and any hydroxyl group on the other glucose unit.
The possibilities of glycosides formation is presented below.
