Explanation:
Detailed explanation-1: -Lactose. Commonly it is called milk sugar as this disaccharide is found in milk. It is made up of Beta-D-galactose and -D-glucose. The bond is between the first carbon of galactose and the fourth carbon of glucose.
Detailed explanation-2: -Lactose is a disaccharide that is made up of glucose and galactose.
Detailed explanation-3: -Lactose is composed of a molecule of galactose joined to a molecule of glucose by a -1, 4-glycosidic linkage. It is a reducing sugar that is found in milk.
Detailed explanation-4: -Lactose is a disaccharide derived from the condensation of galactose and glucose, which form a -1→4 glycosidic linkage. Its systematic name is -D-galactopyranosyl-(1→4)-D-glucose.
