Introduction
Since digestive enzymes actually function outside of the body cells in the digestive tract, their hydrolytic activity can be studied in a test tube. We studied starch digestion by salivary amylase, trypsin digestion of protein and pancreatic lipase digestion of fats. The goal of these tests was to understand the optimal environmental conditions needed for digestive enzymes to function. Additionally, it was the goal of the above experiments to learn the role of temperature and pH in the regulation of enzyme activity.
Starch Digestion by Salivary Amylase--Relevant Observations:
Salivary amylase and pancreatic amylase break down starch.
Boiling the mixtures denatures the enzymes and therefore starch is not reduced to sugar.
The pH of 7 is optimal for reducing starch to sugar.
If the pH is too high or too low starch and sugars will remain present.
Protein Digestion by Trypsin--Relevant Observations:
Trypsin breaks down protein.
When the substrate, BAPNA, was......
