Pepsin Enzyme and pH Lab
This lab is similar to the amylase one except that the action of pepsin will be visualized using Biuret as an indicator solution. Since pepsin is most active in the stomach, students will compare its action under different levels of pH.
Essential concepts:Pepsin, enzymes, pH, protein, amino acids, denaturation.
