Blood: biochemistry - triglycerides

pequis

Overview

  • Most common form in which lipid is stored.
  • Synthesized in:
    • Intestinal mucosa (exogenous triglyceride)   →   carried to tissues as chylomicrons.
    • Liver (endogenous triglyceride)   →   carried to tissues as very low density lipoproteins (VLPL).
  • Both forms hydrolyzed in capillary endothelium by lipoprotein lipase (LPL) and free fatty acids   →   taken into cells.
  • LPL activity increased by insulin, glucagon and thyroid hormones   →   lipemia may indicate decreased activity of one of these hormones or insulin resistance.
