The homeostasis of this element in the body is partially mediated by Repulsive Guidance Molecule C and in the intestines it is transported by DMT1. One protein that regulates this element is made of 24 protein subunits, stores this in the center of a spherical structure as a crystalline solid, and releases this as an ion attached to 6 water molecules. (*) One compound containing this element is bound to by histidine F8 to protein. A protein with it was the first protein to have its structure successfully determined by x-ray crystallography. A related protein can bind this cooperatively and has four subunits. This element's concentration is regulated by ferritin and it is contained in the porphyrin ring heme as part of its role as a carrier for oxygen in hemoglobin. For 10 points, name this element symbolized Fe.
