Query: Determination of some solubilization parameters with surfactants of
  egg-yolk lecithin multilamellar vesicles by static light-scattering
  measurements   Effective surfactant:phospholipid ratios (i.e. molar ratios in the mixed
aggregates, vesicles or micelles) have been determined by static
light-scattering for the interaction of egg-yolk lecithin (EYL) multilamellar
vesicles (MLV) with Triton X-100 (TX-100), sodium deoxycholate (DOCNa) and
cetyltrimethylammonium bromide (CTMB). The suspension of MLV-EYL was mixed with
appropriate volumes of surfactant solution and was left overnight to reaches
thermodynamic equilibrium. Rectan-gular optic diffusion data were used to
compute the solubilization parameters: total surfactant concentrations, at
saturation and solubilization Dtsat and Dtsol respectively, and effective molar
ratios, Resat and Resol respectively. From the Resat value ob-tained
graphically for interaction of vesicles with TX-100 resulted that in vesicle
bilayers a surfactant molecule is surrounded with seven phospholipid molecules
and the Resol value suggests that in mixed micelles ten lipid molecules with
about fifteen surfactant molecules coexist. The values of Resat and Resol in
case of MLV solubilization with DOCNa are 0.07 and 1.1 re-spectively. In case
of vesicles solubilization with CTMB, Resat =0.25 and Resol =3.6 These data
show that the solubilization power at thermodynamic equilibrium for the three
surfactants is in the sequence: CTMB<TX-100<DOCNa.
