The lipoprotein is a combination of protein and a lipid. It is this form that are conveyed fats in blood plasma.
Lipoproteins ensure exchange between the cell and its surroundings. In blood, we distinguish 3 groups:
- the very low density lipoprotein (VLDL) which transport triglycerides (three fatty acids)
- low density lipoprotein (LDL) that carrycholesterol and are large contributors to its deposition on the tissue blood vessels first phase of atherosclerotic lesions
- high density lipoprotein (HDL)
We distinguish now VHDL lipoprotein, high density tend to recirculate cholesterol deposited on the walls of tissue. They are now regarded as a factor in preventing cardiovascular events.
Essential fatty acids (the body can not synthesize) seem the most effective agents for lowering blood cholesterol.
