What are chylomicrons?

Chylomicrons are one of the five types of lipoproteins and are made up of protein and fats.

They are one of the largest lipoproteins which are found in the blood and the lymphatic fluid where they can transport fat from the intestines to the liver and fat stores. They are comprised of about 90% of triglycerides which makes them very floatable.

Where are they made and how?

Chylomicrons are formed in the intestines after digested fat is absorbed. They are then transferred to tissues such as skeletal muscle, body fat, and the liver through the bloodstream. Then, a n enzyme called lipoprotein lipase breaks down the triglycerides in chylomicrons into free fatty acids. These free fatty acids are then either used to produce energy by muscle cells, retained in muscle or fat tissue, or broken down by the liver and converted into other substances.
