lipid digestion

• bile salts emulsify lipids ie split large droplets into small micelles
• 1. lipase digests micelles and releases monoglycerides and fatty acids at epithelial membrane to be absorbed by simple diffusion
• 2. triglycerides are reformed at the SER
• 3. the golgi produces chylomicrons from triglycerides and lipoproteins
• 4. the chylomicrons are exported by exocytosis
• 6. chylomicrons are absorbed by lacteals in the villi
