Abstract
Using a technique for determining Ca and Mg based on Schwarzenberg's method of titration with ethylenediamine tetraacetic acid (EDTA), it was found that glycerol-extracted muscle fibers contain on the average 0.58 millimole Ca and 0.55 millimole Mg per kg. muscle. The fibers take up additional Ca or Mg from dilute solutions of these metals, but in KCl solutions, the excess is exchanged for K ions.Keywords
