Synthesis, Structural, and Catalytic Studies of Palladium Amino Acid Complexes
… acetate and palladium(II) chloride react with amino acids in acetone/water to yield cis or trans square planar bis-chelated palladium amino acid complexes. The naturally occurring amino acids and some N-alkylated and substituted derivatives and homologs were evaluated as ligands. Thirty-eight …

The interaction of cobalt, amino acids, and cobalt amino acid complexes with sediment surfaces
Organic molecules such as amino acids have long been considered the cause of some anomalous behavior of metals in the marine environment, with respect to concentration in the water and adsorption on the sediment. Many studies have investigated the adsorption of amino acids and amino acid complexes. …

Synthesis and characterization of amino acid complexes of physiological metal ions to be used as ergogenic aids
… the treatment of exercise-induced dehydration. Amino acid complexes have been proven to be effective in improving the absorption of various metal ions. Amino acids also play a crucial role in regulating muscle physiology during and after increased muscle exercise. Amino acid-based complexes with …

Oxidative addition of amino acids and other biologically interesting molecules to an iridium metal center
The oxidative addition of amino acids and other biologically interesting molecules to iridium{(I) complexes was studied and the reactivity of the resulting hydrido chelate complexes was investigated. Oxidative addition of amino acids to [Ir(COD)(PMe₃)₃]Cl resulted in the formation of meridional …
