Speciation and structural aspects of interactions of Al(III) with small biomolecules

Hydroxamic Acids − An Intriguing Family of Enzyme Inhibitors and Biomedical Ligands

“…Siderophores also have high affinities for other tripositive metal ions such as aluminium(), but their complexes are less stable than those of iron(). [7] Figure 1. Hydroxamate siderophore, Desferrioxamine B Siderophores and their analogues have vast therapeutic potential, yet few practical applications of siderophores have been realised.…”

Fourier transform Raman spectra (in aqueous solution) of serine and tetraaqua serine aluminium(III) cation complex: [Al(Ser)(H2O)4]2+. DFT: B3LYP/3–21G structural and vibrational calculations

“…There is no evidence for coordination of a COO through both oxygen atoms in aqueous solution for metal-serine complexes. Recently, Rubini et al 3 the possibility of forming the [AlL] C complex. The amino acid serine exists in aqueous solution as the zwetterion HOCH 2 CHNH 3 C -COO which when it dissociates loses an H C to give the species HOCH 2 CHNH 2 COO , indicating coordination by means of the -COO and -NH 2 groups forming ML species.…”

Highly Sensitive Aluminium(III) Ion Sensor Based on a Self-assembled Monolayer on a Gold Nanoparticles Modified Screen-printed Carbon Electrode

“…The positively charge aluminium ion is classified as a typical hard metal ion, and hence is expected to form stable complexes with carboxylic groups containing negatively-charge oxygen. 42,43 The linear dependence of the peak current of a mercaptossuccinic acid gold nanoparticles modified screen-printed carbon electrode after a 10 min preconcentration in 41.4 μM aluminium with the scan rate (Fig. 4) is an indication that Al(III) is tightly bound to the ligand.…”
