Investigating Lipase

Aim

During this investigation my aim is to find out which temperature lipase digests fats into smaller soluble particles best. I will begin by looking at my background information so I can make a justified prediction.

********************************

Background Information

I already know that lipase is an enzyme. Enzymes are made inside cells and once formed can leave the cell, in which it was made to exert its action outside. These enzymes are called extra cellular enzymes. Extra cellular enzymes include enzymes known as digestive enzymes; these enzymes work in the body break down food substances in the gut. Lipase is one of these digestive enzymes. Lipase is an enzyme that works in the small intestine it digests fats into smaller soluble particles called glycerol and fatty acids.

I also know that Lipase works best in neutral conditions.

We are going to use bile in our investigation. Bile is not an enzyme; it emulsifies the fats in the small intestine so the lipase has a greater surface area to work over.

We know from a
