Aim To investigate the effect of the concentration of bile salts on the activity of lipase on the breakdown of milk. Introduction From prior AS knowledge involving biological molecule I know that lipids are broken down into fatty acids and glycerol by the action of the enzyme lipase. Subsequently using this information in the experiment we will be measuring the fall in pH using a pH probe to find the rate of reaction of the experiment. This is because if lipase is breaking down the lipids then the pH should fall and become more acidic as fatty acids which are acidic are being produced. By keeping the variables the same except for the concentration of bile salts we can be able to see what affect, if any the bile salts have on the activity of the enzyme lipase on the breakdown of lipids, with our source of lipids being milk. In addition to...
