Membrane, action, and oscillatory potentials in simulated protocells.
Electrical membrane potentials, oscillations, and action potentials are observed in proteinoid microspheres impaled with (3 M KC1) microelectrodes. Although effects are of greater magnitude when the vesicles contain glycerol and natural or synthetic lecithin, the results in the purely synthetic thermal protein structures are substantial, attaining 20 mV amplitude in some cases. The results add the property of electrical potential to the other known properties of proteinoid microspheres, in their role as models for protocells.
