Summary

THE EXTENT OF DENATURATION OF CARP ACTOMYOSIN IN A POTASSIUM CHLORIDE SOLUTION DURING FROZEN STORAGE WAS MEASURED. FIRST ORDER RATE CONSTANT OF THE ACTIVITY LOSS AT 266 K (-7 DEG C) DECREASED WITH AN INCREASE OF THE CALCULATED CONCENTRATION OF PROTEIN IN THE LIQUID PORTION. SIMILAR RELATIONSHIP WAS OBSERVED AT 268 K (-5 DEG C) AND 253 K (-20 DEG C). THE REACTION OF DENATURATION (DECREASE OF UNCHANGED PROTEIN CONCENTRATION) IN THE LIQUID PHASE WAS OF A LOWER ORDER THAN UNITY AND THE ORDER DIFFERED AT DIFFERENT STORAGE TEMPERATURES. LOG FIRST ORDER CONSTANTS WERE CORRELATED BY A STRAIGHT LINE IN PLOTTING LOG PROTEIN CONCENTRATIONS IN LIQUID PORTION. THE VALUES FOR SLOPES OF THE CORRELATION LINES WERE PROPORTIONAL TO THE STORAGE TEMPERATURE.
