Lipid oxidation catalyzed by the <5 kilodalton (KD) fraction of mackerel ordinary muscle was inhibited by ceruloplasmin and EDTA suggesting the involvement of metals. Removal of ascorbate from the soluble fraction of ordinary muscle decreased FeCl 3 ‐stimulated lipid oxidation suggesting that ascorbate was capable of reducing metals in mackerel muscle. Components with spectral characteristics similar to hydrogen peroxide‐activated hemoproteins were detected in aged mackerel muscle. Stimulation of lipid oxidation by ascorbate and a > 150 KD fraction of ordinary muscle was inhibited by ceruloplasmin suggesting that iron was released from ferritin.
