HYDRODYNAMIC PROPERTIES OF WATER IN MYOPLASM IN RESTING AND ACTIVE STATES

As indicated by the experiment in early days (Ogata, 1965), the electr ical resistance of the myoplasm in resting state is very high compared with that in activated state. This is in accord with the observation that water is only slowly squeezed out from relaxed muscle fragments b y applying pressure, compared with that from the activated muscle frag ments. All these findings suggest that the water in the relaxed fiber is well retained by structural proteins in accord with the structure o f water in resting muscle demonstrated by H-1-NMR studies.
