Statement 1: Maltose is a reducing sugar which gives two moles of D-glucose on hydrolysis.
Statement 2: Maltose has 1,4-$\mathrm{\beta }$-glycosidic linkage.
 

On hydrolysis one mole of maltose yields two moles of D-glucose. It is a reducing sugar. The two glucose units are linked through $\mathrm{\alpha }$-glycosidic linkage between c- I of one unit and the C-4 of another.
