Abstract

Chemical digestion, the decomposition of macromolecules by the action of enzymes, begins in the mouth and stomach but occurs primarily in the small intestine. This exercise shows how to construct a simulated stomach and duodenum using common laboratory equipment and chemicals. The lab clearly demonstrates the effect of a gastric enzyme, pepsin, on proteins while leaving other food substances intact.
