n. a *lipoprotein particle present in the blood after digested fat has been absorbed from the small intestine. The lipid portion consists largely of triglycerides, which are released by the action of *lipoprotein lipase.
These are organized blobs of fats, synthesized in the submucosa of the small intestine out of dietary fats, phospholipids, specialized proteins and cholesterol, carried out of the intestinal tract by the lymph, and slowly released into the bloodstream. In the capillaries, the triglycerides inside the chylomicrons, recognized by their protein markers, are absorbed into the tissues for fuel or storage, and the outside cholesterol and phospholipid transport-cover continues through the blood to be absorbed by the liver for its use. This sideways approach takes (ideally) a large part of dietary fats into the lymph back alleys, spreading their release into the bloodstream out over many hours, thereby avoiding short-term blood fat and liver fat overload. To synthesize the maximum amount of dietary fats into chylomicrons, you need well-organized emulsification and digestion of lipids by the gallbladder and pancreas.... chylomicrons
