Triacylglycerol Fate in Liver and Adipose Tissue

In White adipose tissue , TAG is stored in a nearly anhydrous form as fat droplets in the cytosol of the cells. It serves as “depot fat,” ready for mobilization when the body requires it for fuel. Little TAG is stored in healthy liver. Instead, most is exported, packaged with other lipids and apolipoproteins to form lipoprotein particles called very-low-density lipoproteins (VLDL).

Nascent VLDL are secreted directly into the blood where they mature and function to deliver the endogenously derived lipids to the peripheral tissues.
