Method "Diffusion of small nonelectrolytes through planar lipid bilayer membranes (egg phosphatidylcholine-decane) was examined by correlating [least square regression analysis] the permeability coefficients of 22 solutes with their partition coefficients between water and four organic solvents."
Comments "If solute permeability through a lipid bilayer is governed by the same forces that determine its partitioning into nonaqueous solvents, then pm and Kp should correlate. Figure 2 shows the relationships between membrane permeability and partition coefficients into (a) hexadecane, (b) olive oil, (c) octanol, and (d) ether. The exact values of pm [membrane permeability] and Kp [partition coefficient] are given in Table 1."
