Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion : β-glycosidic linkage is present in maltose,
Reason : Maltose is composed of two glucose units in which C–1 of one glucose unit is linked to C–4 of another glucose unit.
We find α-glycosidic linkage present in maltose.
In maltose, two glucose units are joined by a glycosidic linkage between the α-anomeric form of C-1 on one glucose unit and the hydroxyl oxygen atom on C-4 of the adjacent glucose unit. Such a linkage is called α-1,4-glycosidic bond.
