LIPIDS CLASSIFICATION

LIPIDS CLASSIFICATION

1. Simple Lipids

   • Fatty Acid + Alcohol
   • Triglyceride/Triacylglycerol/Neutral Fat
     • Fatty Acid + Glycerol
     • Fats
     • Oils
   • Waxes
     • Fatty Acid + Cetyl Alcohol

2. Complex/Compound Lipids

   • Fatty Acid + Alcohol + Other Groups
   • Phopholipids
     • Glycerophospholipids
       • Fatty Acid + Glycerol + Phosphate + Nitrogeous Base
         • Lecithin
         • Cephalin
           • Found in cell membrane especially brain
     • Sphingophospholipids
       • Fatty Acid + Sphingosine + Phosphate + Nitrogenous Base
         • Sphingomyelin
           • Found in membranous myelin sheath that surronds the nerve cell axon
   • Glycolipids/Glycosphingolipids
     • Fatty Acid + Sphingosine + Carbohydrate + Nitrogenous Base
       • Cerebrosides
       • Gangliosides
   • Lipoproteins
     • Lipids + Proteins
       • Very Low Density Lipoproteins - VLDL
         • Low Density Lipoproteins - LDL
           • High Density Lipoproteins - HDL

3. Derived Lipids

   • Derivatives obtained by hydrolysis of Simple and Compound Lipids
     • Fatty Acids
