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 …
