and iron(III) because of their high oxidation potentials were the only metals able to induce oxidative decarboxylation of amino acids and formation of Strecker aldehyde or its derivatives as detected by gas chromatography/mass spectrometry. Furthermore, studies performed with synthetic alanine and glycine copper complexes indicated that they constituted the critical intermediates undergoing free-radical

A method for producing amino acid chelate compounds, characterized in that metal oxides and/or metal carbonates and/or metal sulfates and/or metal chlorides and/or metal hydroxides in solid form are activated mechanically and then the activated metal oxides and/or metal carbonates and/or metal hydroxides and/or metal sulfates and/or metal chlorides are brought together with amino acids in solid form and converted to amino acid chelate compounds in a solid-state reaction.
Abstract Mannich aminomethylation reactions involving bis(glycinato)metal(II) (metal = zinc, nickel, copper and cobalt), formaldehyde and acetamide result in the formation of the respective metal(II) complexes of ( N,N -di- N ′-methylacetamido)glycine, which are characterized by various physical means, including X-ray structural analyses of the zinc(II) and nickel(II) complexes.
