The diagram below illustrates the basic structure. Let's start off with food intake. There are many different fats such as cholesterol, triglycerides, fatty acids and phospholipids. The proper scientific term for fats is lipids. The lipids, in particular, cholesterol and triglyceride are then incorporated and made into spherical particles called lipoproteins.
Lipoproteins are the carriers of cholesterol and triglyceride.
They are then secreted by the intestinal mucosal cells into the blood circulation. These lipoproteins are specifically called chylomicrons. The way they deliver cholesterol and triglycerides to the tissues is a complex process. The tissues contain specialized enzymes called lipoprotein lipase. When the chylomicrons enter the tissues, lipoprotein lipase 'grab' the chylomicrons and they cause 'break-down' of the triglycerides in the core of the chylomicrons into their structural components which are the free fatty acids.
