Review on iron and its importance for human health

Biochemistry and physiology In contrast to zinc, iron is an abundant element on earth[2,9] and is a biologically essential component of every living organism[10,11] However, despite its geologic abundance, iron is often a growth limiting factor in the environment[] This apparent paradox is due to the fact that in contact with oxygen iron forms oxides, which are highly insoluble, and thus is ....
