Two types of lipid peroxidation protection factors were found in rainbow trout white muscle cytosol. One type of protection factor is heat‐labile and nondialyzable. This type of protection factor could be superoxide dismutase, catalase, or a yet uncharacterized proteinaceous factor. The other type is heat‐resistant but dialyzable. Iron chelating reagent, such as inorganic phosphate could belong to this type of protection factor. Both types are glutathione (GSH)‐independent and preserve polyunsaturated fatty acid in fish muscle microsomes. This indicates that these protection factor are able to prevent the initiation of lipid peroxidation of polyunsaturated lipids.
