Question

Answer the following question.
Write the products obtained after the hydrolysis of lactose.

Answer 1

Lactose is composed of β-D galactose and β-D glucose. Thus on hydrolysis, it gives β-D galactose and β-D glucose. 

\[\ce{\underset{\text{Lactose}}{C12H22O11}+\underset{\text{Water}}{H2O}->\underset{\text{D-Glucose}}{C6H12O6}+\underset{\text{D-Galactose}}{C6H12O6}}\]
