Lactose on hydrolysis yields
2 molecules of fructose
2 molecules of glucose
One molecule of glucose and one molecule of fructose
One molecule of glucose and one molecule of galactose
Lactose i. It is the sugar present in milk. It is a reducing disaccharide. On hydrolysis, lactose yields glucose and galactose. Beta glycosidic linkage is present in lactose. ii. The anomeric carbon atom of beta-galactose is attached to the 4th hydroxyl group of glucose through beta-1,4 glycosidic linkage. The lactose may be alpha or beta variety, depending on the configuration of 1st carbon of glucose moiety.Ref: DM Vasudevan, 7th edition, page no: 77
