[Structure and metabolism of plasma lipoproteins]

Blood plasma contains lipoproteins of which the structure and the composition are not constant during the time and that depend on their metabolic evolution from their synthesis rate in intestine or liver to their utilization in the liver or the peripheral tissues. The composition and the pathway of the different lipoprotein classes (chylomicrons, VLDL, LDL, HDL) are reviewed, as also the main pathological perturbations that attack them.
