Lactose contains$\mathrm{\alpha }-$glycosidic linkage between${\mathrm{C}}_1$of galactose and${\mathrm{C}}_4$of glucose

Lactose is a reducing sugar and it gives Fehling's test.

Lactose$\left({\mathrm{C}}_{11}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\right)$is a disaccharide and it contains$8$hydroxyl groups.

On acid hydrolysis, lactose gives one molecule of$\mathrm{D}\left(+\right)-$glucose and one molecule of$\mathrm{D}\left(+\right)-$galactose.
