Detailed explanation-1: -Normally upon lactose consumption, it is hydrolyzed into glucose and galactose by the lactase enzyme, which is found in the small intestinal brush border. Deficiency of lactase due to primary or secondary causes results in clinical symptoms.

Detailed explanation-2: -Lactase is an enzyme. It breaks down lactose, a sugar in milk and milk products. Some people’s bodies do not make enough lactase, so they are not able to digest milk well, which can lead to diarrhea, cramps, and gas. This is referred to as “lactose intolerance.” Taking supplemental lactase can help break down lactose.

Detailed explanation-3: -The hydrolysis of lactose to glucose and galactose is catalysed by enzymes called -galactosidases which are found in animals, plants and microorganisms. However, in industry, only the enzymes from microbial sources are used for lactose hydrolysis (Vasiljevic and Jelen, 2002).
