the significant differences noted in the lipid class and molecular species distribution suggest that the true transformations of the lipoproteins are much more complex and may also involve cholesteryl ester-triacylglycerol , triacylglycerol and phosphatidylcholine exchanges via appropriate carrier plasma proteins , as well as possible phase separation of lipids during the removal of the excess surface material from the vldl remnants , as already demonstrated in in vitro experiments .
