[Fat stabilizing action of phosphatides. Part 3. Synergistic action of various phosphatides].

Phosphatides do not regnerate tocopherol worn with supplying oxygen; their synergistic action seems to be a reaction competing with that of hydroperoxide with tocopherol and, consequently, it must be regarded as "tocopherol-saving". Phosphatide mixtures act to some extent as metal capturers. Their effects are functions of the heavy metal contents of the substrates and of their contents of specific metallic pro-oxidants and must be attributed to more complex carbohydrate-containing compounds; phosphatidyl choline and ethanolamine are not able to form metal complexes.
