  2. Salt bridge (protein and supramolecular) - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge_(protein_and...

    To maintain the salt bridge, His31 will attempt to keep its proton as long as possible. When the salt bridge is disrupted, like in the mutant D70N, the pK a shifts back to a value of 6.9, much closer to that of His31 in the unfolded state. The difference in pK a can be quantified to reflect the salt bridge’s contribution to free energy.

  3. Salt bridge - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge

    In electrochemistry, a salt bridge or ion bridge is an essential laboratory device discovered over 100 years ago. [ 1 ] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell .

  4. DNA separation by silica adsorption - Wikipedia

    en.wikipedia.org/wiki/DNA_separation_by_silica...

    A chaotrope denatures biomolecules by disrupting the shell of hydration around them. This allows positively charged ions to form a salt bridge between the negatively charged silica and the negatively charged DNA backbone in high salt concentration. The DNA can then be washed with high salt and ethanol, and ultimately eluted with low salt.

  5. Liquid junction potential - Wikipedia

    en.wikipedia.org/wiki/Liquid_junction_potential

    The most common method of eliminating the liquid junction potential is to place a salt bridge consisting of a saturated solution of potassium chloride (KCl) and ammonium nitrate (NH 4 NO 3) with lithium acetate (CH 3 COOLi) between the two solutions constituting the junction. When such a bridge is used, the ions in the bridge are present in ...

  6. Cation–π interaction - Wikipedia

    en.wikipedia.org/wiki/Cation–π_interaction

    Bonding energies are significant, with solution-phase values falling within the same order of magnitude as hydrogen bonds and salt bridges. Similar to these other non-covalent bonds, cation–π interactions play an important role in nature, particularly in protein structure, molecular recognition and enzyme catalysis. The effect has also been ...
