Iron is a part of several macromolecules in the human body involved with production of energy by the formation of adenosine triphosphate molecules, ribonucleoside reductase activity in DNA synthesis and xenobiotic metabolism (He et al, 2007; MacKenzie et al, 2007).The macromolecules consist of hemoglobin, cytochromes, oxygenases, flavoproteins, and redoxins. This makes iron a significant part of the vital biologic processes in human beings. Iron has a dichromatic nature; it is able to participate favourably in production of energy by electron transfer and can be simultaneously toxic by electron transfer in oxidation-reduction reactions (MacKenzie et al, 2007).
