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 .
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.
Example salt bridge network in 2-deoxyribose-5-phosphate aldolase ( ). Interactions are shown as cyan dashed lines. Polar residues are colored green. Polar amino acids aspartate (D), glutamate (E), lysine (K), and arginine (R), are shown here. Salt bridges within TIM barrel pores are thought to contribute to the overall stability of the fold.

The salt bridge may be replaced periodically but contamination of the other electrolytes will persist. How is this handles if for example measurements require a the use of a salt bridge over extended periods? It would be nice if somebody could treat such aspects in the article.150.227.15.253 09:26, 20 May 2020 (UTC)
Hashiwokakero (橋をかけろ Hashi o kakero; lit. "build bridges!") is a type of logic puzzle published by Nikoli. [1] It has also been published in English under the name Bridges or Chopsticks (based on a mistranslation: the hashi of the title, 橋, means bridge; hashi written with another character, 箸, means chopsticks).
