Ph of the weakest base
WebThe driving force for accumulation of CQ and HCQ is proportional to the square of the hydrogen ion gradient, unlike a monoprotic weak base like NH 4 Cl, which is proportional to the proton gradient. 30 Once protonated, CQ and HCQ are charged and get trapped in the lumen. 30 The ability of CQ and HCQ to raise lysosomal pH suggests that these ...
