NEET BIOLOGY

Detailed explanation-1: -Normally, when we eat something containing lactose, an enzyme in the small intestine called lactase breaks it down into simpler sugar forms called glucose and galactose.

Detailed explanation-2: -How is lactose digested? Lactose digestion occurs in the small intestine with the help of the enzyme known as lactase. Lactase breaks down lactose into the monosaccharides galactose and glucose, which makes them available for absorption.

Detailed explanation-3: -Lactose intolerance occurs when your small intestine doesn’t produce enough of an enzyme (lactase) to digest milk sugar (lactose). Normally, lactase turns milk sugar into two simple sugars-glucose and galactose-which are absorbed into the bloodstream through the intestinal lining.

Detailed explanation-4: -lactase, also called lactase-phlorizin hydrolase, enzyme found in the small intestine of mammals that catalyzes the breakdown of lactose (milk sugar) into the simple sugars glucose and galactose.

Detailed explanation-5: -Lactose is made up of galactose and glucose monosaccharide units.
