Lipids

• Products of lipid digestion are fatty acids, monoglycerides and glycerol
• Monoglycerides and fatty acids associate with phospholipids and bile salts to form micelles: bigger SA
• Micelles aid the transport of monoglycerides and fatty acids to the surface of epithelial cells
• short fatty acid chains within the epithelial cells diffuse into the blood stream
• longer fatty acid chains recombine with monoglycerides and glycerol to form triglycerides in the smooth endoplasmic reticulum
• Triglycerides are packaged into lipoproteins called chylomicrons
• Chylomicrons hold non-polar triglycerides inside them
• Chylomicrons enter the bloodstream
