because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the experiment I have used buffer solutions with the pHs of 2.8‚ 4 and 6.5. I have also used iodine and starch. Normally‚ iodine is orange-yellow‚ however when you add starch to it‚ the solution will turn blue-black. Aim: The aim for this experiment is to investigate how the different buffer solutions work on the enzyme amylase. This will be investigated by using iodine and by timing the experiment using

HARTSELL Laboratories of Bacteriology‚ Department of Biological Sciences‚ Purdue Univer8ity‚ Lafayette‚ Indiana Received for publication October 28‚ 1951 Since the initial discovery of lysozyme by Fleming (1922)‚ nuimerous attempts have been made to describe the properties of this enzyme. The absence of a reliable method for the determination of enzymatic activity‚ however‚ has contributed to the incompleteness and

Joanne Kathleen Saori T. Suzuki‚ Laurent Santos‚ Val Justin D.M. Tongco* College of Science‚ University of Santo Tomas‚ Manila Philippines Abstract Salivary amylase‚ found in humans‚ is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors‚ such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. However
