An investigation to find the effect of bile salts on the digestion of fats.

... AN INVESTIGATION TO FIND THE EFFECT OF BILE SALTS OF ON THE DIGESTION OF FATS Proposed method I intend to investigate the effect of bile salts on the digestion of fats. I will make up different concentrations of bile salts and add them to a lipase and fat (in this case full fat milk) mixture. I will then measure the digestion of fats by measuring the amount of fatty acids produced during the breakdown, which will be shown as a change in pH. I predict the weaker the concentration of bile salts, the slower the digestion of fats, i.e. the pH change will occur slower. Scientific background to the method Bile is an important part of the digestion of fats. It is made in the liver, and is stored in the gall bladder. Bile contains bile salts, electrolytes, bilirubin, cholesterol, and phospholipids.1 The bile salts are mainly derived from Sodium glycocholate and sodium taurocholate. The
