Triglyceride (TG). a water-insoluble energy-rich lipid. is secreted by the liver as part of very low density lipoproteins (VLDLs) to supply energy to extrahepatic tissues. Overproduction of VLDL is associated with increased risk of cardiovascular heart disease; this has renewed an interest in factors that affect hepatic TG production. https://www.itsmajorlook.com/
