    Summary
    This summary is machine-generated.

    Plasma transports lipids like free fatty acids, triglycerides, and cholesteryl esters using albumin and lipoproteins. Specialized lipoproteins, including chylomicrons and HDL, manage the transport and exchange of these essential lipids throughout the body.
