Detailed explanation-1: -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. Sucrose is composed of a molecule of glucose joined to a molecule of fructose by an -1, -2-glycosidic linkage.

Detailed explanation-2: -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.

Detailed explanation-3: -lactose, carbohydrate containing one molecule of glucose and one of galactose linked together. Composing about 2 to 8 percent of the milk of all mammals, lactose is sometimes called milk sugar. It is the only common sugar of animal origin.

Detailed explanation-4: -As a disaccharide consisting of glucose and galactose, lactose acts as an energy-carrier in milk.

Detailed explanation-5: -Lactose is a reducing sugar composed of one molecule of D-galactose and one molecule of D-glucose joined by a -1, 4-glycosidic bond (the bond from the anomeric carbon of the first monosaccharide unit being directed upward). Many adults and some children suffer from a deficiency of lactase.
