EFFECT OF FREEZING RATE ON THE DENATURATION OF MYOFIBRILLAR PROTEINS.

Author(s) : WAGNER J. R., ANON M. C.

Type of article: Article

Summary

FREEZING OF BOVINE MUSCLE HAS A DENATURATING EFFECT ON MYOFIBRILLAR PROTEINS. DIFFERENTIAL SCANNING CALORIMETRY STUDIES OF FRESH AND FROZEN MUSCLE AT DIFFERENT FREEZING RATES SHOW A DECREASE ON DENATURATION ENTHALPIES ; THE LOWER THE FREEZING RATE THE GREATER THE LOSS. WHEN MEASURING THE SPECIFIC AREAS OF THE THERMOGRAMS, IT CAN BE OBSERVED THAT THE AREA ASCRIBED TO MYOSIN DECREASES WITH FREEZING, WHILE THE AREA CORRESPONDING TO ACTIN IS NOT AFFECTED. THESE RESULTS ARE IN AGREEMENT WITH THE ATPASE ACTIVITY DECREASES.
