By means of a mathematical model of the non-facilitated passive trans-membrane microtransport, the influence of the relaxation time of the various ions on the dynamics of cell parameters is demonstrated. Through the equating of the unfacilitated trans-membrane microtransport across the cell membrane with the relaxation process in a polarized electrolytic cell, the experimental determination is sought of the relaxation time for the solutions of unsaturated fatty acids esters with cholesterol in glycerol. The influence of the compound nature on its concentration on the relaxation time is found.
