when the beta-vldl were hydrolyzed by lipoprotein lipase in the presence of density greater than 1.21 g/ml lipoprotein-deficient plasma , the addition of normal apo-e ( apo-e3 ) , but not apo-e2 , resulted in a shift of fraction ii particles to the low density lipoprotein ( ldl ) range ( approximately equal to 1.05 g/ml ) .
