[Size, structure, and dynamics of bile salt/lecithin mixed micelles (author's transl)]

The structure and size of lecithin/sodium glycocholate mixed micelles was investigated by quasi-elastic laser light scattering and spin label techniques. The investigations are in accordance with a bilayer model for these micelles. The order parameter and the phase transition enthalpy of the micellar bilayer were determined. The lateral and rotational diffusion constants of label molecules are compared with the corresponding diffusion constants in liposomes.
