    Study Notes

    Simple Lipids

    • Primarily composed of carbon, hydrogen, and oxygen.
    • Fundamentally composed of fatty acids and glycerol.

    Waxes

    • Simple lipids consisting of long fatty acid chains attached to a long-chain alcohol.
    • Esters of fatty acids with monohydric alcohols with high molecular weights.

    Complex Lipids

    • Esters of fatty acids that also contain other chemical groups in addition to glycerol and fatty acids.
    • These groups can include phosphates, sugars, and nitrogen.
