Emulsification Bile acts to some extent as a Fat Fat surfactant,helping to Watery emulsify the fats in the food. GI juices Bile Bile salt anions have a hydrophilic side and a hydrophobic side,and Enzymes therefore tend to aggregate around droplets of fat (triglycerides and 瓷 平 Enzyme phospholipids)to form Emulsified fat micelles,with the hydrophobic sides towards 终 the fat and hydrophilic 数 towards the outside
