Abstract
Magnesium therapy (infact prophylaxis, suppression of stress symptoms etc.) has proven successful on using complexes of magnesium with natural amino and polycarboxylic acids. Presumably their activity is due to formation of weak complexes, from which the magnesium is released again after transport. As has now been demonstrated, L‐aspartic acid reacts as a di‐ to tridentate ligand depending on the pH. On the basis of X‐ray crystallographic, spectroscopic and electrochemical data, a model has been designed which is consistent with medicopharmacological findings.
