Phytic acid (myo-Inositol hexakisphosphate) (IP6)

Phytic acid (myo-Inositol hexakisphosphate, IP6) is a highly phosphorylated molecule found abundantly in plant seeds, serving as the main storage form of phosphorus[1][5]. It possesses six phosphate groups, giving it strong negative charges and chelating properties, especially towards mineral ions such as calcium, iron, and zinc[1][6]. In plants, it serves as a phosphate and energy reserve; in animals and humans, it is not digestible from food but can be synthesized in cells[1]. Phytic acid acts as a dietary antioxidant and has been investigated for its potential anti-cancer, anti-inflammatory, and metabolic benefits[2][6][8]. However, its strong binding affinity to minerals may reduce their bioavailability, raising nutritional concerns about mineral deficiencies if consumed excessively[2][6]. Overall, phytic acid is a biological molecule with nutritional, biochemical, and clinical significance, but it is not considered a conventional therapeutic target for drugs such as receptors or enzymes[1][5][8].
