Iron transport and storage

Free Course Free Course

This free course, Iron transport and storage, looks at the methods that have been developed by organisms for the uptake, transport and storage of iron: a process made more complicated by the insolubility of its oxides and hydroxides. You will examine iron storage in mammals, including humans,. This is achieved by ferritin which stores iron as a hydrated iron (III) oxide an example of biomineralisation.

After studying this course, you should be able to:

  • describe some of the biochemical methods by which organisms uptake iron
  • describe some of the biochemical processes by which organisms store and transfer iron
  • explain why iron is present only in very low concentrations in aqueous solution
  • use aspects of iron(III) chemistry to explain the role of macrocyclic ligands in iron uptake and transfer.

Iron transport and storage

Introduction

Unit image

In this course we will see that, despite having a high natural abundance, iron is in very short supply because of the insolubility of its oxides and hydroxides. A result of this is that organisms have developed methods for the uptake, transport and storage of iron. For example, iron storage in mammals, including humans, is achieved by ferritin, which stores iron as a hydrated iron(III) oxide – an example of biomineralisation.
