plasma lipoprotein mass concentrations were measured by analytic ultracentrifugation for flotation rates ( f0 ( 1.20 ) , s0f ) within high density lipoprotein ( hdl ) ( f0 ( 1.20 ) 0-9 ) , low density lipoprotein ( ldl ) ( s0f 0-12 ) , intermediate density lipoprotein ( idl ) ( s0f 12-20 ) , and very low density lipoprotein ( vldl ) ( s0f 20-400 ) particle distributions .
