Apoprotein exchange between human high-density-lipoprotein subfractions (high-density-lipoprotein subfractions 2 and 3) [proceedings].

centrifugation restored these increases when included in the heparin-containing medium at concentrations of 10-8Opg of protein/ml. The ability of heparin to stimulate the release of lipoprotein lipase from human adipose tissue in vitro has been demonstrated by several groups of workers (Elkeles, 1974). That this release can be closely correlated with triacylglycerol clearance provided further evidence of the central role played by this enzyme in the transfer of triacylglycerol from blood to peripheral tissues. Serum lipoproteins appear to have a role in potentiating the release of the enzyme from the tissue.
