Physiology of Lipid Metabolism
Lipids are insoluble in water and are therefore associated with serum
lipoproteins to facilitate their transport in blood.

The Fredrickson classification of hyperlipidemia describes six characteristic
patterns of changes in the individual lipid moieties. HDL is not considered in
this classification system. This is not a diagnostic classification and does
not distinguish between primary and secondary hyperlipidemias or accurately
predict risk of future coronary heart disease events.
