Interaction of l-arginine with dihexadecylphosphate unilamellar liposomes: the effect of the lipid phase organization

Interaction of an organic cation with Gibbs monolayers of n-hexadecyl phosphate

“…It has been reported that an amino acid, L-arginine (L-arg) is perceived to function as L-argininium cation (L-arg + ) at a pH lower than 11.0 (pK = 12.48) and undergoes association with n-alkyl phosphates to form salts [36,37]. The bulk phase behavior of these salts has already been detailed [37][38][39]. Since the bulk phase and the adsorption layers at the airwater interface are intercorrelated, an obvious interaction of L-arg + with these monolayers is expected to take place.…”

Effect of electromagnetic field and surface modification on the electrical behavior of novel solid lipid nanoparticles covered with l-arginine

“…This implied that guanidinium group in l-arginine could preferentially bind to phosphate group of phospatidylcholine on the SLNs with the residual portion of l-arginine toward the aqueous phase. Also, phase transition in the lipid bilayer might alter the binding constant between l-arginine and phosphate group on lipids [33]. In this study, the variation in the electrical properties of the argininemodified SLNs was indiscernible in the range of  between 40% and 50%.…”

Surface phase behavior of di-n-tetradecyl hydrogen phosphate in Langmuir monolayers at the air–water interface

“…On the other hand, di-n-alkyl phosphates (DAP) having analogue molecular structure of phospholipids have mostly been used to form vesicles to mimic the cell membrane [9]. Reports on size and shape of the vesicles of the latter group of amphiphiles and their interactions with different organic molecules and inorganic ions have readily been available in the literature [10][11][12][13]. However, studies on the properties of the DAP monolayers have largely been ignored.…”
