Abstract:

An instrument to measure pulsed nuclear magnetic resonance NMR relaxation times of biological potassium 39K has been constructed. NMR relaxation times of 39K have been measured in muscle, brain and E. Coli bacteria, and has been found to be much shorter than for 39K in free solution, approaching the short values observed for 39K complexed by ion exchange resin. This evidence suggests that potassium ion in cells is associated with fixed charge groups on macromolecules and is not in free solution. Solid state physical analyses of biological systems have suggested that detection of weak magnetic fields 0.5-1.0 gauss by living organisms may occur by superconductive Josephson junctions constructed of organic molecules, and that piezoelectricity and pyroelectricity may participate in force and temperature detection by nerve receptors.
