In the study of autoxidation of fats and oils, it is necessary to investigate the deterioration of fatty acids composed these fats and oils, because the oxidative rancidity largely depends upon the presence of unsaturated fatty acids. In this report the following experiments are involved. 1. Polarographic observation of mixed fatty acid separated from fish oil. From this experiment the polarographic wave having a half-wave potential of -1.9V observed in oxidized mixed fatty acid as samely obtained in oxidized fats and oils. 2. Polarographic observation of oxidized unsaturated fatty acids. The similar reduction wave observed in oxidized unsaturated fatty acid and separated carbonyl group. Therefore it is considered that the polarographic wave which was reduced at the potential of -1.9V vs S. C. E. in oxidized oil is caused by the carbonyl compound produced during the oxidation.
