Table 2: Plasma Lipoprotein Classes.

Lipoprotein	Origin	Size (nm)	Density (g/ml)	Predominant Lipids	Major Apoliproprotein
Chylomicron	Intestine	75–1,200	<0.930	Triglycerides	apoB48
Chylomicron Remnant	Chylomicron metabolism	30–80	0.930–1.006	Triglycerides Cholesterol	apoB48
VLDL	Liver	40–50	0.930–1.006	Triglycerides	apoB100
IDL	VLDL	25–35	1.006–1.019	Triglycerides Cholesterol	apoB100
LDL	IDL	18–25	1.019–1.063	Cholesterol	apoB100
HDL	Liver, intestine	5–12	1.063–1.210	Cholesterol Phospholipids	apoA-I
Lp(a)	Liver	20–30	1.055–1.085	Cholesterol	apo(a)

apoB100 = apolipoprotein B100; apoB48 = apolipoprotein B48; apoA–I = apolipoprotein A–I; apo(a) = apolipoprotein(a); HDL = high-density lipoprotein; IDL = intermediate-density lipoprotein; VLDL = very low-density lipoprotein.
