WebJul 16, 2024 · Ovotransferrin is an iron-binding protein that is extremely sensitive to heat. The capture/release of charge causes the oxidation/reduction of iron ions in ferritin. Using the exchange characteristics of the ion itself, iron ions can be easily replaced by different kinds of transition metal ions [ 46 ]. WebOvotransferrin has strong affinity towards iron, as it contains charged amino acid residues that bind to iron. Ionization of these residues is affected by variations in pH and this effect can be seen in the extraction runs, where pH has been varied keeping other parameters (ethanol and FeCl 3 ) constant. folly farm food menu
