Abstract Interactions of lecithin dissolved in alkane with polar solvents and phosphatidyl-ethanolamine have been studied by means of IR and NMR spectroscopy. Comparison of gelforming compounds with sructurally related ones incapable of inducing jellification of lecithin solutions has provided an insight into the molecular organization of polymerlike micelles. In a developed... 

We have recently ascertained [4, 5] that in addition to water a few polar organic solvents are capable of inducing the jellification of lecithin solutions. Their comparison with nongel-forming structural analogue provides an insight into the mechanism of processes at the molecular level. 

In this dissolution model, resistance occurs at the crystal-solution interface. When dissolution rate constant is plotted against angular velocity the positive intercept on the vertical axis indicates interfacial resistance (Figure 1)[9]. Detachment of Ch molecules from the surface of the cholesterol disk (or Ch stone) is a slow process and can be influenced by the presence of lecithin in BS micelles. Higuchi et al. have shown that dissolution of ChM crystals by cholate-lecithin solutions is unaffected by variations of angular...

As a uniform director alignment is required to measure the refractive indices fi and fio, the surface of the main prism is pre-treated to align the director homeotropically by using lecithin solution.
