chylomicron
Chylomicrons (from the Greek chylo, meaning ''juice'' or ''milky fluid'', and micron, meaning ''small particle'') are lipoprotein particles that consist of triglycerides (85–92%), phospholipids (6–12%), cholesterol (1–3%), and proteins (1–2%).〔M Mahmood Hussain: "Review Article: A proposed model for the assembly of chylomicrons"; Arterosclerosis; Vol. 148; 2000; pages 1–15;〕
They transport dietary lipids from the intestines to other locations in the body. Chylomicrons are one of the five major groups of lipoproteins (chylomicrons, very low-density lipoprotein, intermediate-density lipoprotein, low-density lipoprotein, high-density lipoprotein) that enable fats and cholesterol to move within the water-based solution of the bloodstream.
==Function==
Chylomicrons transport lipids absorbed from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by the activity of lipoprotein lipase and the released free fatty acids are absorbed by the tissue. When a large portion of the triacylglycerol core have been hydrolyzed, chylomicron remnants are formed and are taken up by the liver, hereby transferring dietary fat also to the liver.
