Answer:
lactose
Explanation:
Lactose is a disaccharide sugar made up of glucose and galactose monosaccharide subunits. In lactose, galactose and glucose molecules form a covalent glycosidic bond denoted as an (β-1→4) glycosidic bond. Lactase is an enzyme that hydrolyzes lactose into glucose and galactose, which can be then absorbed into the bloodstream by the cells lining the small intestine. In an alkaline solution, lactose may also isomerize to generate a mixture of lactulose (20-30%) and lactose (70-80%).
