The purpose of this study was to determine the tissue-specific acquisition of antioxidant capacity during chick embryo development and to assess the effectiveness of this process in the prevention of lipid peroxidation. The transfer of α-tocopherol, carotenoids and ascorbic acid from the yolk/yolk sac membrane (YSM) to the developing chick embryo and the distribution of these antioxidant compounds...
The present work studies the degradation kinetics of α-tocopherol in hydrophilic gels incorporating vitamin C as antioxidant. HPLC was used to detect the amounts of α-tocopherol remaining and to validate the analytical and extraction techniques. The results indicate that α-tocopherol undergoes degradation by oxidation of the hydroxyl group, and that this is reduced by the presence of the antioxidant.
