Description and Uses

Ferric citrate (iron (III) citrate) is prepared from reaction of citric acid with ferric hydroxide. It is a compound of indefinite ratio of citric acid and iron. Ferric citrate is slowly soluble in cold water, readily soluble in hot water, and practically insoluble in alcohol.

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.
