LipoproteinsCholesterol is the main sterol of the human body. And even though it is usually believed that cholesterol must be eliminated, it should be clarified that this sterol has important functions in the organism, it being a component of various tissues, mainly those of the brain, the medulla, the nervous system, the liver and the blood. It happens that, in order for them to exercise these functions, cholesterol is transported via the bloodstream by means of the lipoprotein molecules. The lipoproteins are classified according to their composition, size and proportions of fat (lipids), and the protein contained in them. This classification occurs in the following manner:
kµ, Kilomicrons ?
VLDL, Very Low Density Lipoprotein ?
LDL, Low Density Lipoprotein little protein and more lipids, less dense and less heavy ?
HDL, High Density Lipoprotein - much protein and little fat. The proteins make the molecule denser and heavier.
