http://shipin.hzau.edu.cn/info/1170/8025.htm WebWhile egg yolks are naturally iron-rich, eggs contain a protein called phosvitin that binds up the high iron content, making it less available for digestion. Phosvitin in eggs may also prevent the ...
Phosvitin iron
Did you know?
WebPhosvitin is a small (∼5–20 kDa) YP made up mainly of long stretches of extensively phosphorylated serine residues, empowering Pv to bind calcium, magnesium, zinc, and iron via ionic interactions. 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 contains about 110 phosphoserine residues (50% of its amino acids), responsible for its iron binding capacity (Itoh et al, 1983). What is egg phosvitin? Phosvitin is one of the egg (commonly hen’s egg) yolk phosphoproteins known for being the most phosphorylated protein found in nature. …
WebPhosvitin is a small (∼5–20 kDa) YP made up mainly of long stretches of extensively phosphorylated serine residues, empowering Pv to bind calcium, magnesium, zinc, and iron via ionic interactions. In freshwater fishes, these ions delivered to the yolk by Pv may be crucial as they are largely unavailable for uptake from the environment. 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.
