A mesofase liotropica it is generated from mesogeni that disciolti in dissolvent appropriating, and in it determines concentration intervals to you, become a member of in liquid-crystalline structures.
Often the mesogeni liotropici they are anfifiliche molecules (that is they contain is groups works them idrofobici that idrofilici). To varying of the concentration of the dissolvent (water in this case) the idrofiliche or idrofobiche property can vary, modifying the way in which molecules they become a member of between of they and in connection with molecules of the dissolvent.
The degree of order of aggregation of these molecules increases increasing of the concentration, and exists numerous possibilities of micelle aggregation, between which as an example:
* Spherical
* Colonnare
* Cubical
* Lamellare
Numerous tensioatti to you they show this type of behavior and they are organized in micelles when disciolti in water. The operation of many soaps is based on this ability to organize itself in spheroidal micelles that inglobano the fat person rimuovendolo from the dealt surface.
Also in Biology they are met mesogeni liotropici: as an example numerous substances been involved in the mechanism of biological membranes, the proteins that constitute the burlap of the spider, some virus, the phospholipids and the same DNA.
