The size distribution of aggregates in amphiphilar systems are computed on the basis of statistical thermodynamics. Numerical calculations have been carried out for alkyl glucosides and sodium alkyl sulfates. In these cases the computations show that the amphiphilar solution consists of single amphiphiles and only a narrow size range of aggregates. A critical concentration, defined earlier, cor...

Rat liver glucokinase (EC 2.7.1.2) is inhibited specifically by the free form of palmitoyl-CoA (Ki apparent of approximately 1.8 PM) and other related long chain fatty acyl-CoAs under conditions where the micellar form of these compounds does not exist. This inhibition is instantaneous, and is immediately reversible by dilution, bovine serum albumin, and aor B-cyclodextrins. Inhibition is speci...

Alternative methods for determining the critical micelle concentration (cmc) are investigated using canonical and grand canonical Monte Carlo simulations of a lattice surfactant model. A common measure of the cmc is the "free" (unassociated) surfactant concentration in the presence of micellar aggregates. Many prior simulations of micellizing systems have observed a decrease in the free surfact...

Modelling of the critical micelle concentrations (cmc) using the molecular connectivity indices was performed for a set of 21 cationic gemini surfactants with medium-length spacers. The obtained model contains only the second-order Kier and Hall molecular connectivity index. It is suggested that the index 2χ includes some information about flexibility. The obtained model was used to predict log...

Non-ionic surfactants, poly oxyethylene sorbitan adipose acid esters (polysorbate), were used in this work to explore the consequence of temperature on CMC throughout a wide range. The phase separation model is analyze enthalpy and entropy micelle conformation. Du Nöuys ring was determine results' face pressure. standards derived after strong break down surfactant attention plots pressure vs. l...

The effect of toluene solubilization on the size and mobility of Triton X100 (TX100) micelles and TX100/sodium dodecyl sulfate (SDS) mixed micelles was studied by turbidimetry, dynamic light scattering, and capillary electrophoresis. Micelle growth due to toluene solubilization was observed for both surfactant systems; however, two different modes of growth were seen. Mixed micelles in 0.1 M Na...

The detailed aggregation behavior of sodiumdodecyl sulfate (SDS) in tetrahydrofuran (Tf)-water (W) and formamide (Fa)-water (W) media at varied volume percent compositions has been investigated. Surface tension (ST), conductance (Cond), viscosity (Visc), isothermal titration calorimetry (ITC), nuclear magnetic resonance (NMR) and small angle neutron scattering (SANS) were used in this study. Th...
