Good sources of dietary iron include meat, beans, and leafy vegetables however, excessive amounts of iron in the body can lead to cell damage and eventually.
In mammals and other animals, hemoglobin is the iron-containing metalloprotein that carries oxygen in red blood cells. This broadening was found to be largely due to coupling between the 2p core-hole and the unpaired 3d electrons of the photoionized Fe cation, as well as electrostatic and crystal field interactions. Immediately obvious is the increased peak width of the Fe 2p 3/2 peak in figure 3. High spin iron compounds are where things become tricky. Post-print standardized by MSL Academic Endeavors, the imprint of the Michael Schwartz Library at Cleveland State University, 2017.)/RD/Rect/Subj(Typewritten Text)/Subtype/FreeText/T(libuser)/Type/Annot> Iron is a necessary trace element used by all known living organisms. Vanadium phosphate glasses containing Fe2O3 with the chemical composition (Fe2O3)x(V2O5)0.6x(P2O5)0.4, where x0.00, 0.10, 0.20, 0.25 and 0.30, have been prepared and investigated by X-ray photoelectron spectroscopy (XPS) and magnetic susceptibility measurements.
