Ferrichromes
Ferrichrome is a cyclic hexa-peptide that forms a complex with iron atoms. It is a siderophore composed of three glycine and three modified ornithine residues with hydroxamate groups [-N(OH)C(=O)C-]. The 6 oxygen atoms from the three hydroxamate groups bind Fe(III) in near perfect octahedral … See more Ferrichrome is a siderophore, which are metal chelating agents that have a low molecular mass and are produced by microorganisms and plants growing under low iron conditions.
