CLASSICALLY, there is a direct correlation between the lipophilic nature of a molecule and its rate of permeation across a biological membrane,1,2 so cell membranes should be more permeable to small, neutral molecules than they are to charged molecular species of similar size. Consequently, the distribution of NH4+ in biological systems is generally… CONTINUE READING
