Analysis Note
Phytic acid is present in all eukaryotic cells. In plants, it is known to function as a [PO4]³⁻ storage depot and precursor for other inositol phosphates and pyrophosphates. Its high surface negative charge makes it a potent chelator of divalent and trivalent cations in vitro, and it is most likely associated with Ca²⁺ or Mg²⁺ ions in vivo. In yeast, phytic acid acts with the nuclear pore protein Gle1 to regulate the nuclear export of mRNA by coactivating the RNA-dependent ATPase activity of DExD-box protein 5 (Dbp5).

General Description
Phytic acid is a major determinant of zinc bioavailability.

Packaging
10, 25, 100, 500 g in glass bottle

Application
Phytic acid has been used in a study to assess the common bean’s potential as a vehicle for iron biofortification. It has also been used in a study to investigate the effects of antinutritional factors on plasma lipoprotein levels.
