The gel to liquid-crystal phase transition in dimyristoylphosphatidylcholine liposomes was studied with 0.4-Hz ac calorimetry. The ac heat capacity on heating scans exhibited a peak in the vicinity of 23.9 degrees C with a full width at half-maximum of 0.15-0.20 degrees C. The enthalpy change was 4.8 kcal/mol, in good agreement with conventional differential scanning calorimetry. On cooling scans, the peak shifted to lower temperature by 0.1-0.5 degrees C, the width increased to 0.25-0.40… CONTINUE READING
