Explanation:
Detailed explanation-1: -Lactose* is a sugar found in milk and milk products. The small intestine produces lactase, an enzyme that breaks down lactose. The small intestine is an organ that breaks down the food you eat. Enzymes are proteins that help to cause chemical changes in the body.
Detailed explanation-2: -The enzyme lactase breaks down milk sugar (lactose). Lactase enzymes are found in the lining of the small intestine. They change the milk sugar into absorbable compounds – glucose and galactose. If your body does not produce enough lactase, lactose is not digested and absorbed in the small intestine in the usual way.
