Routes of nonelectrolyte permeation across epithelial membranes

  title={Routes of nonelectrolyte permeation across epithelial membranes},
  author={Ernest M Wright and Richard J Pietras},
  journal={The Journal of Membrane Biology},
Radioactive tracer techniques were used to study the permeability of three epithelial membranes, the toad urinary bladder, frog choroid plexus, and rabbit gallbladder, to 16 nonelectrolytes. The general patterns of nonelectrolyte permeation were similar for all three membranes, and similar to those in other biological membranes. The permeability of lipophilic solutes was roughly proportional to their bulk phase oil/water partition coefficients, but the slope was greater in the toad bladder than… CONTINUE READING
