Dear student,

The digestion and absorption of lipids is an important function of the liver. Bile acts as a surfactant, helping to emulsify the fats in the food. Bile salts anions have a hydrophilic side and a hydrophobic side, and therefore tend to aggregate around droplets of fat formed micelles, with the hydrophobic sides towards the fat and hydrophilic towards the outside. The hydrophobic sides are positively charged due to the lecithin and other phospholipids that compose bile, and this charge prevents fat droplets coated with bile from re- aggregating into larger fat particles. The dispersion of food fat into micelles thus provides a largely increased surface area for the action of the enzyme pancreatic lipase thus aiding in the digestion of lipids.
