Abstract
The aggregation properties of diacyl phosphatidyl cholines (PC) with symmetric chains of 8–18 carbons in length and diacyl phospholipids with differing head groups (PC versus phosphatidyl ethanolamine (PE) versus phosphatidyl glycerol (PG) were examined using the techniques of quasi-elastic light scattering (QELS) and freeze fracture microscopy. All of these lipids except for the short chain C8PC (where C8 denotes 8 carbon chains) and CPC form multilamellar vesicles. Within this series we observed a positive correlation between most probable vesicle size and acyl chain length. For lipids with identical acyl chains there was an inverse correlation between vesicle size and effective head group cross-sectional area. We envisage a scheme in which the size of liposomes is determined by the area and thickness of multilamellar sheets which occur upon hydration of the dried lipid.
