The time course of passive transport of low-molecular mass substances in a nonequilibrium system of alternating aqueous and lipidic phases was expressed as function of physico-chemical properties of the biosystem (phase volumes, interface area, diffusion layer thickness) and of the transported compounds (diffusion coefficients, partition coefficients).
