The interaction of ions with phosphatidylcholine bilayers

Study of the Reaction 2-(p-Nitrophenyl)Ethyl Bromide + OH− in Sulfobetaine Aqueous Micellar Solutions in the Presence and Absence of Added Salts

“…, [1] where the subscripts w and m denote the aqueous and micellar pseudophases, respectively, and [SB3-14 m ] is the concentration of micellized surfactant, equal to the total surfactant concentration minus the cmc. PE refers to the organic substrate.…”

“…Despite the bindings appearing to be an electrostatic, ion specificity cannot be neglected. 1 To whom correspondence should be directed. E-mail: moya@cica.es.…”

“…The binding of ions to zwitterionic interfaces is well known (1,2). Recently, various studies have reported surface enrichment of ions in sulfobetaine aqueous micelles (3)(4)(5)(6)(7).…”

Effects of ytterbium ion on the growth, metabolism and membrane fluidity of Tetrahymena thermophila

“…Rare earth ions mainly react with lecithoid group. The reaction between rare earth ions and lecithoid polarity head group caused that the alignment of lecithoid molecular was closer, the sport of the fat chain were restricted and the rigidity of the whole membrane increased [21,22]. All these facts indicated that rare earth ions could be membrane active molecules with its effect on cell membranes as fundamental aspect of its toxicity.…”

Studies on the Toxic Effects of La3+ to Tetrahymena thermophila by Microcalorimetry

“…Rare earth ions mainly react with lecithoid groups. The reaction between rare earth ions and lecithoid polarity head groups caused the alignment of lecithoid molecular to be closer, the sport of the fat chain to be restricted, and the rigidity of the whole membrane to increase [24,25]. All these facts indicate that rare earth ions can be membrane-active molecules with its effect on cell membranes as a fundamental aspect of its toxicity.…”
