|
lactase breaks down lactose into galactose and glucose
|
|
|
lactase speeds up the breaking down of lactose
|
|
|
lactase has a specific substrate called lactose
|
|
|
lactase is an enzyme that can break down multiple sugars
|
Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Detailed explanation-4: -Because of enzyme specificity, our bodies need lots of different enzymes to digest different types of food molecules. For example, our small intestine has the enzyme lactase to digest lactose and a different enzyme to digest sucrose.
