  • Lactose is not a simple sugar. It is a disaccharide. Lactose is a complex sugar composed of two different simple sugars: glucose and galactose. These sugars are linked together by a glycosidic bond. Lactose is a disaccharide because it is composed of two sugars. Therefore, the body must split the disaccharide into simple sugars in order for the sugars to be absorbed.
