Phosvitin iron
WebThe phosvitin itself has a strong attraction to metal ions and is difficult for the body to digest, resulting in much of the calcium and iron present in eggs to simply pass through the body. 36 Once the phosvitin is broken into phosphopeptides the real work begins. WebPhosvitin demonstrated higher capacity to inhibit iron catalysis of phospholipid oxidations (up to 30:1 Fe2+-to-phosvitin molar ratio) than copper catalysis (1:1 molar ratio). Pasteurization did not change the antioxidant activities of phosvitin; however, autoclaving decreased phosvitin's inhibitory capacity on iron catalysis. MeSH terms

In freshwater fishes, these ions delivered to the yolk by Pv may be crucial as they are largely unavailable for uptake from the environment.
WebPhosvitin, a phosphoprotein known as an iron-carrier in egg yolk, binds almost all the yolk iron. In this study, we investigated the effect of phosvitin on Fe (II)-catalyzed hydroxyl radical ( (.-)OH) formation from H (2)O (2) in the Fenton reaction system. WebPhosvitin, a hen egg yolk phosphorylated protein, also exists in fish eggs. While their iron binding capacities were studied for the hen, few studies were undertook with fish phosvitin, except for common species like salmon and trout. Consequently, to evaluate better the potential of iron binding of fish phosvitins, it was necessary to have ...
