Product Details

Explore the roles of enzymes and the chemical reactions involved in the human digestive system. The lab starts with amylase, which catalyzes the initial breakdown of starch molecules in the mouth. Students then observe the reaction of the enzyme pepsin with protein molecules in an acid environment, just like in the stomach. Finally, students analyze the “digestion” of milk by lipase, which catalyzed the hydrolysis of milk fat into fatty acids in the small intestine. Iodine, Benedict's reagent, biuret test solution, and litmus are included in the kit, along with the enzymes to test for the end products of digestion. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. Boiling water baths are required for the Benedict's test.
