Does anybody know a general equation for passive membran transport (without specific transporters) of nonpolar molecules which takes into consideration 1. membran properties (lipid composition, thickness, viscosity...) and 2. the properties of the substance (size, molecular weight, partition coefficient, geometry...) ?
