    Study Notes

    Lipids

    Triacylglycerols (Triglycerides)

    • Esters of glycerol with three usually different fatty acids.
    • Main lipids in the body and in food.

    Phospholipids

    • Esters of glycerol with fatty acid, having an additional phosphate group.
    • Include:
      • Phosphatidylcholines (Lecithins).
      • Phosphatidylinositol.
      • Cardiolipin.
      • Lysophospholipids.
      • Plasmalogens.
      • Sphingomyelins.

    Glycolipids

    • Lipids with a carbohydrate attached to them.
    • Widely distributed in every body tissue, particularly in nervous tissue.
