The dietary fats are transmitted from GIT to adipocytes in the form of
TG derived from intestinal absorption of fats are transpoed in the blood as a lipoprotein complex called chylomicrons. Chylomicrons are small microscopic paicles of fats, about 1m in diameter and are responsible for transpo of exogenous (TG) in the blood. * Similarly, TG that are synthesised in Liver cells is conveed to lipoprotein paicles, called very low-density lipoproteins (VLDL) and thrown into the circulation. VLDL is mainly concerned with transpo of endogenous TG. In addition to above: * Fatty acids released from adipose tissue by hydrolysis of TG are thrown in the circulation as free fatty acid (FFA). They are carried in non-esterified state in plasma, hence also called NEFA. In circulation, FFA/ NEFA combines with albumin and are carried as albumin-FFA complex. Some 25 to 30 mols of FFA are present in combination with one mol. of albumin.Ref: Textbook of Medical Biochemistry 8th Edition Dr (Brig) MN Chatterjea, Rana Shinde page no: 445
