What is this in chemistry?

The term salty bridge has two different uses in chemistry. The original use was described by an electrically conductive gel union between two half cells of the Valtaic cell in the electrochemistry. The second is the use of an external, slightly polar molecule to create a bridge between parts of macromolecules that would repel each other without the intervention of the salt bridge. New fields, supramolecular chemistry, in practical development since 1960, use salt bridges to create highly detailed structures.

In the Valtaic Cell, also called Galvanic Cell, an electrochemical reaction takes place in two separate physical places called half cells. Half of the oxidation reduction (redox) reaction occurs in each half of the cell. Alessandro Volta showed the basic principle by stacking zinc and silver discs, separated by paper discs saturated in salt water, bridge, about 1800. By composing several of these sets of zinc bridge, which was able to detect electric shock when touched both ends at the same time. Every metal beltU was soaked in a solution of its own metal ion. Both strips were connected by a wire and both solutions by a porous ceramic tube filled with salt water, a salt bridge.

If the battery cell does not use a salt bridge, the reaction occurs directly and the flow of electrons cannot be directed by wire. The faded bridge only carries out a charge on the ion through its salt ions. No ions from a redox reaction travel through the bridge.

Supramolecular chemistry provides an innovative approach to nanotechnology. Nanoparticle structures, 1 to 100 nanometers (0.00000004 to 0.0000004 inches) are usually made by undressing larger structures by bombing electron or other technology. Supramolecular chemistry attempts to create structures by imitating the natural way of self -establishment. Self-setting occurs when macromolecule puts by adding basic components to a gradual procedure. Acquires new units thatAgain, it causes the molecule to fold and bends in a way to attract and connect another component, finally reaches a precise three -dimensional structure.

deoxyribonucleic acid (DNA) is assembled in the cell itself by the process of folding and re -blocking. When each fold is created, new functional groups, side groups of more reactive atoms are inserted into the attraction or repellent position. As the molecules move to allow functional groups closer or further apart, a fold is made. Hydrogen bond, weak intermolecular or, in the case of macromolecules, weak intramolecular attraction between slightly negative hydroxyl groups and slightly positive proton groups controls the folding process.

occasionally needs a fold or bending in natural or synthetic macromolecules at a place where there are slight repulsive forces. The second small molecule, called the salty bridge, can match the right place where it can bridge contradictory forces. Instead of opening my ownYB, as the unbridled section does, the salt bridge turns the gap and cinches in the macromolecule. The choice of salt bridge is very demanding; Accurate customization is required physically and distribution in charge. Supramolecular chemists study natural macromolecules to understand and use salt bridges in the construction of useful nanostructures.
