Chylomicrons (from the Greek χυλός, chylós, meaning juice (of plants or animals), and micron, meaning small), also known as ultra low-density lipoproteins (ULDL), are lipoprotein particles that consist of triglycerides (83–92%), phospholipids (6–12%), cholesterol (1–3%), and proteins (1–2%). They transport dietary lipids, such as fats and cholesterol, from the intestines to other locations in the body, within the water-based solution of the bloodstream. ULDLs are one of the five major groups lipoproteins are divided into based on their density. A protein specific to chylomicrons is ApoB48.
