Phytic Acid

The Imbibition of Pea (Pisum sativum L.) Seeds in Silver Nitrate Reduces Seed Germination, Seedlings Development and Their Metabolic Profile

“…So far, the involvement of phosphoric acid in pea’s response to environmental stresses remains unclear. In addition to the presence in the form of phytic acid, phosphorus compounds play a crucial role in plants’ metabolism as sugar phosphates as well as phospholipids and nucleotides [ 82 ].…”

68Ga‐Ca‐phytate particles: A potential lung perfusion agent of synthetic origin prepared in a cold kit format

“…The mole ratio of Ca:phytate was [2.3:1] for PHYTATE Radpharm, and the reaction worked equally well at [4.2:1] for PHYTACIS. As the reaction was conducted in strong acid at 100°C for 30 minutes, it may be possible that a phosphate group dissociated from the cyclic structure because it was previously shown that inositol hexaphosphate converts to the pentaphosphate derivative in pH 1 at 110°C in a sealed tube with a rate constant of k = 4 × 10 − 4 min −1 . However, our results using paper chromatography identified 68 Ga‐radioacivity in the dispersion were primarily associated with particulate material (94% RE in rxn 10).…”

“…Heat drove the reaction toward particle formation, and this was confirmed by the ITLC assay to occur with >95% efficiency (rxn 27). Trivalent cations such as 68 Ga 3 + coordinate across hydroxyl‐oxygen atoms of phosphate groups in phytic acid, and these groups are arranged in a 1× axial and 5× equatorial conformation in acidic solvent . The 5× axial and 1× equatorial conformation dominates in basic solution, a structural arrangement also known for the Cu 6 ‐phytate complex .…”

“…Phytic acid or myo ‐inositol hexaphosphate exists abundantly in soils and throughout the plant kingdom, especially in seeds and grains, serving as a principal energy storage form of phosphorus that supports life. Because of its metal chelating properties, it occurs frequently in nature as a heterometal salt of calcium and magnesium, although other metal salts are also known . Phytic acid is used in conjunction with phytase in feed for poultry to improve growth and digestibility, to prevent corrosion of cellulose by metalo‐gallate inks during the conservation of historic papers, as a metal scavenger in topical cosmetics, a corrosion inhibitor of metal surfaces, and as a radiopharmaceutical cold kit in diagnostic nuclear medicine.…”

Release of P from Pyrolysis, Combustion, and Gasification of Biomass—A Model Compound Study

“…Most of the P in the grain- and seed-originated biomass is present in the form of phytate, the salt form of phytic acid, as shown in Figure . For many cereals and oilseeds, the phytate content is normally in the range of 1–3 wt % and accounts for 60–90% of the total P content in the seed. , Phytate has also been shown to be the major P source in chicken litter and accounts for some of the P content in, for example, cattle and swine manure because it is not fully digested . Apart from acting as a P storage and energy depot, phytate, with its six phosphate groups, can bind several cations with multiple charges and, therefore, also act as storage for metal ions such as Na, K, Mg, Ca, Fe, and Zn .…”
