Ascorbic acid and copper in linoleate oxidation. II. Ascorbic acid and copper as oxidation catalysts

open access: yesJournal of Lipid Research, 1969
Both ascorbic acid and copper were strong prooxidants in the oxidation of linoleate in a buffered (pH 7.0) aqueous dispersion at 37°C. Minimum concentrations at which catalytic activity was detected were 1.3 × 10-7m for copper and 1.8 × 10-6m for ...
