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.

Packaging

5 g in poly bottle

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).

Phosphatases, including phytases, play a major role in cell metabolism, phosphorus cycle, biotechnology, and pathogenic processes. Nevertheless, their discovery by functional metagenomics is challenging. Here, soil metagenomic libraries were successfully screened for genes encoding phosphatase activity. In this context, we...
