Lactase (a member of the beta-galactosidase group of enzymes) splits milk sugar (lactose) into the two simple sugars glucose and galactose. Found exclusively in mammalian milk, lactose is only one sixth as sweet as cane or beet sugar (sucrose).
Infant mammals nurse on their mothers to drink milk, which is rich in lactose. The intestinal villi secrete the enzyme called lactase (Î²-D-galactosidase) to digest it. This enzyme cleaves the lactose molecule into its two subunits, the simple sugars glucose and galactose, which can be absorbed. Since lactose occurs mostly in milk, in most mammals, the production of lactase gradually decreases with maturity due to a lack of continuing consumption.
