Chylomicron is the Microscopic Particle of Fat Present in the Blood
Chylomicron is the form in which fat is transported from the gut to the rest of the body. It is relatively large droplets that may contain triglycerides, phospholipids, and cholesterol in association with proteins; synthesized and released by intestinal cells and transported to the venous blood via the lymphatic system. Chylomicrons are around 100 nm across and are formed in the intestinal mucosa, from where they enter the lacteals and eventually the bloodstream. Chylomicrons are produced by the epithelial cells of intestinal villi after long chain fatty acids and monoglycerides have diffused across the microvilli. They form chyle within the lacteals.
