Nettet(1) Lactose contains a-glycosidic linkage between C1 of galactose and C4 of glucose. (2) Lactose (C11 H22 O11) is a disaccharide and it contains 8 hydroxyl groups. (3) On acid hydrolysis, lactose gives one molecule of D (+)-glucose and one molecule of D (+)-galactose. (4) Lactose is a reducing sugar and it gives Fehling's test. jee main 2024 Nettet8. mar. 2024 · Lactose is milk sugar. The enzyme lactase breaks down lactose into glucose and galactose, which are easily digested by humans. Regular milk contains a high concentration of lactose but no glucose, so whichever tube had regular milk should have had a negative reaction with the glucose test strip.
