People with Crohn's disease may develop lactose intolerance caused by damage to their small intestine. These

people may take a commercial product called Lactaid to prevent digestive upset when consuming dairy prod-

ucts. What is in Lactaid that helps these people avoid those symptoms? Explain how this relates to what you

learned about the specificity of enzymes for substrates in this lab.

Lactaid is a medication that contains the milk protein digesting enzyme Lactase. It is an enzyme supplement for those people who have trouble in digesting milk and other dairy products. Such condition occurs in Crohn's disease and termed as lactose intolerance. Lactase specifically acts on the lactose containing substrates and digests them by enzymatic activity. So people with lactose intolerance can be able to take dairy products with the help of Lactaid.
