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.

A Yusuf Boyd, NASM Elite Trainer , Athletic Training, answered. You should ice injuries for 20 minutes and allow at least 1 hour before icing again. The reason for icing is to decrease inflammation and/or pain in the affected area. The way it works is the ice lowers body temperature around the affected area, decreasing blood flow which in turn helps to reduce swelling.
