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. WebHigh-density lipoprotein, or HDL: Made from a high proportion of protein with minimal triglycerides and cholesterol. When you eat, the small intestine takes the cholesterol and triglycerides from your food and packages them using chylomicrons to transport lipids into your bloodstream, and ultimately to your cell tissues. icd 10 pulmonary infiltrates
