Iron cannot be transported around the body's circulation system as free iron, since it would be susceptible to chelation by siderophores, or may precipitate as iron(III) oxide, or may form iron(II). Therefore, a specific transport protein is required, called transferrin. (In fact, a whole class of transferrin-like proteins is involved in iron transport.) Transferrin is a medium-sized protein with a relative molecular mass of about 80 000.
Important: Do not reset your ice maker more than one time in a twenty-four hour period. in the ice tray over filling. If the ice tray over fills, water will pour directly into the ice bucket and freeze. the ice bucket is frozen you will not be able to dispense ice.
