Enzymatic Digestion of
Starch and Protein Lab
This is a second followup to the biologically important molecules lab, this time placing a focus on the digestive activity of enzymes. Students will conduct hydrolysis reactions of proteins using pepsin and starch using amylase. The solutions will be tested for simple sugars, starch and protein before and after completion of the hydrolysis reactions by using the iodine, Benedict's, and Biuret tests.
Essential concepts: Macromolecules, organic molecules, monosaccharides, polysaccharides, proteins, amino acids, enzymes, digestion, hydrolysis.
