Chylomicrons are small particles made of lipids (fats) and proteins that transport dietary fats from the intestines to other parts of the body. They are formed in the intestinal cells after eating and play a crucial role in the absorption of fats and fat-soluble vitamins, such as vitamin A, D, E, and K. Once formed, chylomicrons enter the lymphatic system and eventually reach the bloodstream. They deliver triglycerides to tissues, where they can be used for energy or stored for later use. After their job is done, remnants of chylomicrons are taken up by the liver for further processing.
