RV McDaniel, S. A. Simon,* T. J. McIntosh, and V. Borovyagin* abstract: The thermal and structural properties of saturated phosphatidylcholine liposomes are significantly altered by benzene. Upon the addition of benzene, the liposomes first swell and then disperse into small multilamellar vesicles. At 20 C these vesicles contain striations or ripples in the plane of the bilayer. Major changes in the thermal behavior of DSPC-benzene liposomes occur near mole ratios of 2: 1 and 1: 1. At a 2: 1 mole ratio, the area under the main endothermic peak, AHm, essentially disappears; however, the total heat absorbed, AH (, remainsapproximately equal to that of the control. This occurs because for benzene mole fractions 0.12< x< 0.50, benzene increases the apparentmolar heat ca-pacity, Cp, of the gel phase to about 1.2 kcal/(mol-deg). We interpret thisincrease in heat capacity to be due to an increase in the concentration of defects (or disorder) in the gel phase. At mole fractions of benzene between 0.5 and 0.9, the transition temperature decreases by 20-30 C, and broad, multiple
