Abstract

The authors have studied experimentally the direct passage of the fat-soluble ion tetraphenylboron through artificial phospholipid membranes. As a result this enabled them to determine the diffusion coefficient of tetraphenylboron in the membrane D = 4 × 10-12 cm2/sec, the partition coefficient η = 400, the dielectric constant of the region of the polar groups ε ≈ 13 and the surface capacitance of the membrane C~10 μF/cm2.
