Description

<jats:title>Abstract</jats:title> <jats:p>Complete formation of the most stable lamellar crystal (Lc2) phase was achieved for dipalmitoylphosphatidylglycerol (DPPG) bilayer membrane in 1.0 mol kg−1 aqueous NaCl solution. A peculiar stepwise transition was observed from the differential scanning calorimetric measurements when the Lc2 phase was completely formed. This is probably relevant to the morphological change from rod-like or cylindrical particles to spherical vesicles concomitant with the transition.</jats:p>
