Summary

ENZYMIC LIPID PEROXIDATION BY LIGHT AND DARK MUSCLE MICROSOMES OF HERRING REQUIRED ATP (ADENOSINE TRIPHOSPHATE) OR ADP (ADENOSINE DIPHOSPHATE), NADH (REDUCED NICOTINAMIDE -ADENINE -DINUCLEOTIDE) AND IRON. INHIBITION WAS OBSERVED AT HIGH CONCENTRATIONS OF ADP AND NADH BUT NOT IRON. THE OPTIMAL PH FOR BOTH TYPES OF MICROSOMES WAS BETWEEN 6 AND 7. THE AVERAGE PEROXIDATION RATE WAS 362 AND 1,143 NMOLES MDA (MALONDIALDEHYDE) PER MG PROTEIN PER HR AT 279 K (6 DEG C) FOR THE LIGHT AND DARK MUSCLE MICROSOMES, RESPECTIVELY. THE LIGHT MUSCLE MICROSOMES LOST ACTIVITY FASTER THAN THE DARK MUSCLE MICROSOMES WHEN EXPOSED TO 308 K (35 DEG C). FERROUS ION STIMULATED ENZYMIC LIPID PEROXIDATION OF LIGHT AND DARK MUSCLE MICROSOMES OVER THAT OBSERVED WITH FERRIC ION.
