WebMay 1, 2014 · Abstract. Iron is one of the most important nonorganic substances that make life possible. Iron plays major roles in oxygen transport (eg, hemoglobin; ~67% of total body iron [TBI]), short-term oxygen storage (eg, myoglobin; ~3.5% of TBI), and energy generation (eg, cytochromes; ~3% of TBI). 1 Iron also serves vital roles in various nonheme … Webmelanomacrophages.
