WebChylomicrons enter the liver and are packaged into VLDL. VLDL is involved in the transport of triacylglycerol (TAG) from the liver to extrahepatic tissues. LDL transports cholesterol (so-called bad cholesterol) to tissues and HDL is responsible for “reverse transport” or removal of cholesterol (so-called good cholesterol) from tissues. WebChylomicrons transport food fats perfectly through the body’s water-based environment to specific destinations such as the liver and other body tissues. Cholesterols are poorly absorbed when compared to phospholipids and triglycerides. Cholesterol absorption is aided by an increase in dietary fat components and is hindered by high fiber content. greeting the seasons granby ct
