How Do Enzymes Help People With Lactose Intolerance?

How does the dietary supplement LACTAID work to help people with lactose intolerance? Model the action of the enzyme lactase. Conduct tests to determine whether LACTAID, an enzyme supplement, digests lactose. Design and conduct an experiment to determine if acid interferes with the action of the enzymes in LACTAID. This complete experiment setup contains all materials and does not require lab equipment.
