Reverse micelles as a model system for carbohydrate binding
摘要:
The surfactant sodium 3-[[1,2-bis[[(2-ethylhexyl)oxy]carbonyl]ethyl]thio]succinate (1) aggregates in chloroform/cyclohexane (1:1, v/v) mixture to form inverse micelles. The small-angle X-ray scattering from these solutions indicates that the aggregates are approximately spherical with a radius of gyration that varies from 6.3 to 18.5 angstrom, depending upon the amount of added water. These inverse micelles can bind and solubilize monosaccharides in nonpolar organic solvents. H-1 and C-13 NMR, as well as ESR experiments on these solutions, indicate that monosaccharide derivatives are bound to the surfactant head group at low water content and are solubilized in the water pool at high water content.
