Consider the Benedict result from the four test tubes: (1. water, 2. starch, 3. saliva, 4. saliva + starch) 1) Which one showed presence of sugar? Why not in the others? 2) What was the purpose of dipping in warm water? 3) What was the purpose of the boiling water in the end?
Example1: Glucose Starch Digestion by saliva Amylase Substrate: Starch (Amylose) Products: Glucose molecules
