WebAim: To investigate the effect of pH on the rate of reaction of amylase You will: Use the enzyme amylase to breakdown starch at a range of pH values, using iodine solution as an indicator for the reaction occurring Use a continuous sampling technique to monitor the progress of the reaction WebThe optimum pH of alpha-amylase is 6.7–7.0. Ptyalin is mixed with food in the mouth, where it acts upon starches . Although the food remains in the mouth for only a short time, the action of ptyalin continues for up to several hours in the stomach —until the food is mixed with the stomach secretions, the high acidity of which inactivates ...
