Lipolysis of phospholipids in model cholesteryl ester rich lipoproteins and related systems: effect of core and surface lipid phase state.

Porcine pancreatic phospholipase A2 (PL A2) was used as a probe to study the structure of phospholipid domains of dimyristoylphosphatidylcholine (DMPC) vesicles +/- 2% cholesteryl oleate (CO), of discoidal structures formed by the interaction of apolipoprotein E (apoE) with these vesicles, and of large CO/DMPC microemulsion particles +/- apoE. Results of… CONTINUE READING
