Type of article: Article

Summary

PROTEIN DENATURATION WAS EVALUATED BY MEASURING ACTOMYOSIN EXTRACTIBILITY AND ITS CALCIUM-ATPASE AND MAGNESIUM (EGTA)-ATPASE ACTIVITIES AND ELECTROPHORETIC ANALYSIS. NO CHANGE WAS OBSERVED IN ELECTROPHORETIC PROFILE DURING STORAGE AT -20 DEG C. ON THE OTHER HAND, THE MOLECULAR WEIGHT OF THE HEAVY MYOSINE AND ACTINE CHAIN DECREASES. STUDY OF THE CORRELATIONS BETWEEN THE ADENOSINE NUCLEOTIDE COMPOSITION OF THE MUSCLE AND PROTEIN DENATURATION. MUSCLE WITH HIGH INOSINE AND HYPOXANTHINE CONTENTS BUT LOW ATP, ADP, AMP AND IMP CONTENTS IS THE MOST INSTABLE.
