Proteins in Fish Muscle.: III. Denaturation of Myosin by Freezing

Abstract

The myosin fraction of fish muscle is isolated from the other proteins and is used in a study of denaturation by freezing as determined by solubility changes. The effects of the physical state of the protein, the rate of freezing, and the hydrogen ion concentration have been determined. Ions and salts showed a significant effect when the freezing temperature was lower than the cryohydric points of the salts.
