[In German. / En allemand.]

Author(s) : GOTTESMANN P., HAMM R.

Type of article: Article

Summary

DURING THE STORAGE OF LIVER AT 2 DEG C FOR SEVERAL DAYS, A SIGNIFICANT DECREASE IN THE OVERALL ACTIVITY OF LIPOAMIDE DEHYDROGENASE (LIPDH), A LESS IMPORTANT DECREASE IN THE ACTIVITY OF BETA HYDROXYACYL-COENZYME-DEHYDROGENASE (HADH) AND NO CHANGE IN THE ACTIVITY OF CITRATE SYNTHASE (CS) WERE OBSERVED. THE FREEZING OF BEEF AND PORK LIVER TO -20 DEG C CAUSED SOME LOSS OF THE OVERALL ACTIVITY OF HADH, ESPECIALLY OF LIPDH, BUT NOT OF THE ACTIVITY OF CS. THERE IS A CONSIDERABLE INCREASE IN THE ACTIVITIES OF LIPDH, CS AND HADH IN PRESSED LIVER JUICE. AN ENZYMATIC METHOD IS DISCUSSED FOR STUDYING A DIFFERENTIATION OF UNFROZEN AND FROZEN LIVER. R.R.
