NettetBoth the monosaccharides i.e. glucose and fructose are connected through the glycosidic linkage between alpha glucose and second carbon beta fructose. Sucrose is a non-reducing sugar as both the reducing groups of glucose and fructose are involved in the glycosidic bond formation. Examples of Disaccharides 1. Sucrose NettetSucrose is an alpha-1 to beta-2 linkage (a1->b2) between glucose and fructose. The thing with naming these linkages with regards to the anomeric carbon is not just solely based on if the hydroxyl group is pointing up or down. You also have to look at the terminal carbon and ask whether it's cis or trans from the anomeric hydroxyl group. the most coolest thing
