Detailed explanation-1: -Lactose is a sugar found in milk and milk products. Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase. Lactase breaks down the lactose in food so your body can absorb it.

Detailed explanation-2: -Lactase is an enzyme needed to convert milk sugar (lactose) into simple sugars that the body can use (glucose and galactose). Lactase is produced in the small intestine.

Detailed explanation-3: -Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.

Detailed explanation-4: -Lactase is a disaccharidase enzyme present in the brush border of the small intestinal mucosa that breaks down milk sugar into glucose and galactose so that these can be absorbed [16].

Detailed explanation-5: -The lactase in your small intestine should break lactose down into sugars called glucose and galactose, which are then absorbed into your bloodstream.
