<unk> -density lipoprotein (HDL) does not represent one structure but rather a series of lipoproteins that are sequentially produced.  HDL dynamically switches between different conformations. Fractionated HDL particles can be classified based on physiochemical properties, cholesterol component, apolipoprotein composition, electrophoretic mobility, density, and biological function.  HDL concentration in the serum can be classified into either low and<unk>  when the serum HDL concentration ≥ 60mg/dL and < 40 mg/dL, respectively.
