lactase catalyses hydrolysis of lactose.
Lactase.Lactase is essential for digestive hydrolysis of lactose in milk. Deficiency of the enzyme causes lactose intolerance.
When a molecule of lactose is hydrolyzed the monomers that had linked together to form lactose will be pulled away from each other through the addition of lactose. Lactose is made from GLUCOSE AND GALACTOSE, henceforth these two monomers will emerge through the hydrolysis of lactose. Hope this helps...
Galactose is obtained from lactose (the milk sugar) after its hydrolysis carried out by the enzyme beta-galactosidase (or lactase) yielding beta-D-glucose and alpha-D-galactose.
The principle behind lactose extraction from milk is enzymatic hydrolysis. The enzyme lactase is added to milk, which breaks down lactose into its constituent sugars, glucose and galactose. The chemical reaction can be represented as: Lactose + Water → Glucose + Galactose
That's because the lactose is broken down into two other easily digested sugars which are sweeter: breaks into galactose and glucose... this occurs through hydrolysis in the milk prior to drinking it ( because lactase is found in the milk, which contains lactose), thus creating a sweeter milk).
Acetal formation (glycosidic linkage) between glucose and galactose by condensation reaction.It can also be seen as dimerisation of two monosaccharides (Glu + Gal) to one disaccharide(Lactose is: β-D-galactopyranosyl-(1→4)-D-glucose)
Acidic hydrolysis: hydrolysis in an acid solution (pH under 7) Basic hydrolysis: hydrolysis in a basic solution (pH above 7)

in the hydrolysis of sucrose a catalyst such as sucrase must be applied
LACTOSE sugar
Hydrolysis. Polymers are broken down into monomers in a process known as hydrolysis
