(+) lactose is a $\beta$-glycoside formed by the union of a molecule of $D(+)$ glucose and a molecule of $\mathrm{D}(+)$ galactose

(+) lactose is a reducing sugar and does not exhibit mutarotation

(+) lactose, ${\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}$ contains 8-O $\mathrm{H}$ groups

On hydrolysis (+) lactose gives equal amount of $\mathrm{D}(+)$ glucose and $\mathrm{D}(+)$ galactose
