Question

Name the constituents and type of linkage present in $\alpha$-maltose.

• A. one $\alpha$-D-glucopyranose unit and one $\beta$-D-glucopyranose unit with 1,2 -glycosidic linkage
• B. two $\alpha$-D-glucopyranose unit with 1,2 -glycosidic linkage
• C. two $\beta$-D-glucopyranose units with 1 , 4-glycosidic linkage
• D. two $\alpha$-D-glucopyranose units with 1 , 4-glycosidic linkage

Answer 1

Answer: (D)

Maltose is composed of two $\alpha -D$-glucose units in which $C-1$ of one glucose is linked to $C-4$ of another glucose unit.
