Nature of the gel to liquid crystal transition of synthetic phosphatidylcholines

Proc Natl Acad Sci U S A. 1978 May;75(5):2258-60. doi: 10.1073/pnas.75.5.2258.

Abstract

High sensitivity differential scanning calorimetry is employed in the study of the gel to liquid crystal phase transition of a highly purified sample of dipalmitoylphosphatidylcholine in multilamellar bilayer suspension. It is concluded from the calorimetric data that the purity of the sample is better than 99.94 mol % and that the transition closely approximates an isothermal first-order transition.
