Q. Assertion : Maltose is a reducing sugar which gives two moles of D-glucose on hydrolysis
Reason : Maltose has a$ 1,4-\beta$-glycosidic link-age

AIIMSAIIMS 2004Biomolecules

Solution:

Maltose, a disaccharide $\left( C _{12} H _{22} O _{11}\right)$ is a reducing sugar, which upon hydrolysis yield 2 moles of $D-(+)$-glucose. In it the two $D$-glucose unit are linked through $\alpha$-glycosidic linkage between $C -1$ of one glucose unit and C-4 of the other.
