Digestion of fat starts in the small intestine. Here, bile salts of bile juices emulsify the fats. Triglycerides (emulsified) are incorporated into the small, spherical water soluble, droplets of glycerides, fat soluble vitamins and sterol, which are called micelles. The later are absorbed in the endoplasmic intestinal cells and are resynthesised in the reticulum to form smaller fat droplets called chylomicrons. These chylomicrons are released from intestinal cells to lymph and from lymph and are they transported into the blood stream through lacteals
