Abstract
For aqueous solutions containing vesicles formed by sodium di-n-dodecy lphosphate, the gel-liquid-crystal transition occurs near 35-degrees-C at the temperature T(m). When ethanol is added, T(m) decreases. When sodium chloride is added, T(m) shifts to higher temperatures whereas v ery complex scans with several transitions are recorded when calcium c hloride is added. The complexities are attributed to the binding of Ca 2+ ions by phosphate groups at the vesicle surface.
