Pharmacology Concepts pH, pKa, & Ion-Trapping

In cell biology, ion trapping is the build-up of a higher concentration of a chemical across a cell membrane due to the pKa value of the chemical and difference of pH across the cell membrane. This results in basic chemicals accumulating in acidic bodily fluids such as the cytosol, and acidic chemicals … See more Many cells have other mechanisms to pump a molecule inside or outside the cell against the concentration gradient, but these processes are active ones, meaning that they require enzymes and consume cellular See more Ion trapping is the reason why basic (alkaline) drugs are secreted into the stomach (for example morphine), where pH is acidic, and acidic drugs are excreted in urine where the … See more • Osmosis • Biophysics • Forced diuresis • Henderson-Hasselbalch equation See more WebIMAC is a widely-used method for rapidly purifying polyhistidine affinity-tagged proteins, resulting in 100-fold enrichments in a single purification step.
