A method was devised to prepare the amino acid-iron (II) chelate by a simple electrolysis using amino acid suspended in water as the electrolytic solution and passing a current of ca. 0.07-0.17A./cm2 between iron anode and cathode. In order to study the specific behavior and properties of amino acids during this electrolysis, iron (II) chelates of L-and DL-aspartic acids were examined. It was assumed that L-aspartic acid was coordinated as a ligand with coordination number of three but that DL-aspartic acid was a ligand with coordination number of two.
