Webb8 nov. 2024 · Driving Forces. The permeability of a membrane can be defined as the passive diffusion rate of permeated molecules across the biomembrane. It is unanimously accepted that permeability of any specific molecule depends mainly on charge number, polarity, size, and to some extent, to the molar mass of the molecule. WebbPermeation of NaFlu was shown to depend on the concentration of GSH. The apparent permeability coefficient (Papp) of NaFlu in buffer only was 4.98 ± 0.5*10-6, while in the presence of 0.4% GSH a Papp of 9.31 ± 0.92*10-6 was achieved, representing an enhancement ratio (R = Papp enhancer system/Papp control) of 1.86.
