And what happens is in order to increase the rate and efficiency at which our lipase molecules actually break those ester bonds to form fatty acid and glycerol the liver produces a special type of fluid known as bile. So bile consists of amphipatic molecules such as phospholipids and bile salts and it also consists of hydrophobic molecules such as cholesterol. Now, antipatic simply means these molecules do not only have a hydrophobic section, they also have a hydrophilic section. Now, when bile is produced by the liver it is stalled in the gallbladder. It is stored in the gall bladder and eventually it is released via the common bile duct into the small intestine. Now, once the bile is inside the lumen of the small intestine it basically mixes very well with the fat globules because it contains hydrophobic molecules and this is what breaks down the fat globules into smaller molecules we call emulsion droplets.
