Chylomicron Illustration

Chylomicrons are microscopic particles made up primarily of fat and a small amount of protein.

Chylomicrons are made by cells in the small intestine and released into the bloodstream. Their main purpose is to carry triglycerides and other fats to the liver and other tissues in the body. This image illustrates the formation of a chylomicron in the endoplasmic reticulum.
