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.

A. Assertion and reason both are correct statements and reason explains the assertion.

B. Both assertion and reason are wrong statements.

C. Assertion is correct statement and reason is wrong statement.

D. Assertion is wrong statement and reason is correct statement.

E. Assertion and reason both are correct statements but reason does not explain assertion.

Answer :

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.
