absorption of lipids

• 1. micelles hit epithelial cells and breakdown allowing monoglycerides and fatty acids to diffuse across membranes because they are lipid soluble
• 2. monoglycerides and fatty acids are transported to the ER where they recombine to form triglycerides again
• 3. inside the golgi they bind with cholesterol and proteins and are packaged to form chylomicrons
• 4. chylomicrons travel in a vesicle to the cell membrane and are exocytosed from epithelial cells
• 5. chylomicrons enter lymphatic capillaries called lacteals which transport them away from the small intestine to muscles where the triglycerides can be hydrolysed and fatty acids used by the tissues
