    Study Notes

    Classes of Lipids

    • Lipids: Biomolecules predominantly soluble in nonpolar solvents; generally insoluble in water, playing crucial roles in energy storage and cell structure.

    Types of Lipids

    • Wax:

      • Similar to esters with extended R groups, leading to insolubility.
      • Functions include protection and waterproofing surfaces.

    • Triacylglycerols (Triglycerides):

      • Composed of glycerol bonded to three fatty acids through ester linkages.
      • Primarily responsible for energy storage in the body.

    • Glycerophospholipids:

      • Made from glycerol, with two fatty acids and a phosphate group linked to an amino alcohol.
      • Essential for forming cell membranes, providing structure and protection.

    • Sphingolipids:

      • Feature a sphingosine backbone resembling an "L" shape, connected to a fatty acid and a phosphate-amino alcohol.
      • Important for the integrity of nerve cell membranes.

    • Steroids:

      • Characterized by four fused carbon rings; lack fatty acid structures.
      • Serve as hormones that regulate various biological functions.

    • Prostaglandins:

      • Derived from fatty acids, having a unique 5-membered ring structure with two chain-like appendages.
      • Act as localized chemical messengers with hormone-like effects.
