Presentation Transcript

  1. LIPID TRANSPORT Lipoproteins • Lipids are transported in the blood as lipoproteins • are soluble in water because the surface consists of polar lipids.

  2. Combine lipids with proteins and phospholipids. Lipids: Cholesterol Cholesteryl esters Triacylglycerols Phospholids lipoproteins Apolipoproteins + Lipid transport

  3. There are 4 types of lipoprotein • The lipoprotein formed depends on the constituent protein and lipids protein triglyceride Chylo VLDL LDL HDL

  4. Composition of lipoproteins
