The Uses of Iron(III) citrate

Iron(III) Citrate is an integral part of the structural basis of gating by the outer membrane receptor FecA from Escherichia coli. Binding of ferric citrate triggers a conformational change of the extracellular loops that close the external pocket of FecA.

Biochem/physiol Actions

Ferric citrate is used as a component of protein-free medium. It is used as a substitute for transferrin in mouse hybridomas culture. Ferric citrate enhances IgM production. It indirectly stimulates the mitogen-activated protein kinase (MAPK) by favoring high amphiregulin oncoprotein levels in colon cancer.? Ferric citrate is effective in binding to phosphate in patients with dialysis-dependent chronic kidney disease.
