Beschreibung

General description

Phytic acid is a major determinant of zinc bioavailability.

Application

Phytic acid has been used in a study to develop a novel method to reduce fishy aftertaste in wine and seafood pairing. It has also been used in a study to investigate biochemical and nutritional characterization of dry and processed seeds.

Biochem/physiol Actions

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).
