Effect of Anion Triiodide on the Main Phase Transition of Fully Hydrated   Dipalmitoylphosphatidylcholine Bilayers
  The paper describes the effect of anion I-3 on thermotropic mesomorphism of fully hydrated dipalmitoylphosphatidylcholine bilayers. The biphasic behaviour of melting temperature - I-3 concentration dependence and the increase of DELTA T values with I-3 concentration (DELTA T = melting temperature - freezing temperature) suggest the appearance of interdigitated phase of bilayers induced by I-3 ions.
