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.
Selective precipitation of proteins.
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...

The 2 mono saccharides that make up lactose are glucose and galactose. Glucose is basically sugar in its most basic form. It is made by plants through photosynthesis.
Agarobiose, the repeating unit of Agarose, is a disaccharide composed of D-galactose and 3,6-anhydro-L-galactose
Hydrolysis of lactose yields glucose and galactose, while hydrolysis of sucrose yields glucose and fructose.
Lactose is a disaccharide composed of glucose and galactose. Upon hydrolysis, lactose breaks down into its component monosaccharides, glucose, and galactose. This process is catalyzed by the enzyme lactase.

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

Selective precipitation of proteins.
Lactase catalyzes the hydrolysis of lactose, a disaccharide found in milk, into its constituent monosaccharides, glucose and galactose. This enzymatic reaction allows for the digestion and absorption of lactose in the small intestine.
When enzymatic hydrolysis of fatty acids occurs, it releases free fatty acids which are weak acids. These free fatty acids can then ionize in the solution, releasing hydrogen ions which lower the pH. As more enzymatic hydrolysis occurs and more fatty acids are released, the concentration of hydrogen ions increases, leading to a decrease in pH.
