Document Summary

When tg are broken down into small intestine, and mixed with cholesterol, fat soluble vitamins and bile. Process of emulsification that allows absorption of fat (gets close to brush border to diffuse in) Scfa & mcfa are water soluble and are absorbed by microvilli to blood cells. Lcfa and chol are not water soluble and must be incorporated into lipoproteins (protein carrier) Transport particles of water insoluble lipids (wil) Created by combining wil, phospholipids and protein and transport from. 4 types (vary by size and density) chylomicrons (biggest), very low density lipoproteins (vldl), ldl and hdl. All contain protein and lipid the more protein the higher the density. Combo of triglycerides, cholesterol, phospholipids and little protein. Largest lipoprotein is ldl it has the least amount of protein. Help transport lcfa into lymphatic system bloodstream (skips the liver) As it circulates lipoprotein lipase breaks it down into ffa and glycerol and released into cells. Liver is an major lipid producing organ.
