Résumé

The purpose of this Doctoral Thesis is to complete the knowledge of the biological activity of phytate, which is a molecule that has recently demonstrated unknown properties as an inhibitor of pathological calcifications. First of all, three analytical methodologies are presented for the simple and sensitive determination of myo-inositol and phytate at physiological levels. Next, oral and topic absorption of phytate are studied, evaluating its effects on the prevention of subepithelial dystrophic calcifications. Finally, it is demonstrated in a long-term study that oral phytate at high doses does not provoke bioavailability problems and, on the other hand, the effects of different phytate salts on urinary calcium reduction are studied, being potassium phytate the most effective salt.
