Biochemistry · Basic Sciences

How it begins

A comprehensive molecular analysis of iron balance. From the chemical coordination of the d orbitals of ferrous and ferric ions, through the mechanisms of enterocyte absorption, the plasmatic transport complex mediated by transferrin, to the exquisite systemic hormonal regulation exerted by hepcidin and the intracellular feedback controlled by the IRE/IRP system.
