WebFeb 1, 2001 · Erythrocytes, which contain ∼80% of the body's functional iron, have a mean functional lifetime of 120 d in humans. About 85% of the iron derived from hemoglobin degradation is rereleased to the body in the form of iron bound to transferrin or ferritin. Each day, 0.66% of the body's total iron content is recycled in this manner (Finch et al ... WebBelow 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite. It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below.
