Lipoproteins are the transport form of fat in the blood. They contain protein, triglycerides, cholesterol, fatty acids, phospholipids, fat soluble vitamins, steroid hormones and other compounds. The high the protein amount, the high the density.
- VLDL (very low density lipoproteins)-carries
triglycerides to the tissues for use.
- LDL (low density lipoproteins)-helps
carry cholesterol into cells. High levels
of this in the blood are associated with atherosclerosis
and heart disease.
- HDL (high density lipoproteins)-this
helps carry cholesterol away from tissues to
the liver for removal from the body. High
levels protect the body from heart disease.
