because several classes of lipoproteins , including low-density lipoproteins ( ldl ) , very-low-density lipoproteins , and chylomicron remnants , are taken up by means of the ldl receptor , and because ldl and very-low-density lipoproteins , but not high-density lipoproteins , stimulate pg synthesis , we have suggested previously that pg formation is directly linked to the ldl pathway .
