Hydrolysis of lactose yields:

Step-by-step solution

Lactose is a disaccharide composed of -D-galactose and -D-glucose units linked by a -1,4-glycosidic bond. Hydrolysis of lactose with dilute acid or the enzyme lactase yields an equimolar mixture of D-glucose and D-galactose. C ₁₂ H ₂₂ O ₁₁ (Lactose) + H ₂ O H ^+ C ₆ H ₁₂ O ₆ (D-glucose) + C ₆ H ₁₂ O ₆ (D-galactose) Answer: Glucose and galactose
