abstract：:The major net flux of cholesterol in the intact animal or human is from the peripheral organs to the liver. This flux is made up of cholesterol that is either synthesized in these peripheral tissues or taken up as lipoprotein cholesterol. This study investigates whether it is the concentration of apolipoprotein (apo) ...
