Phytic acid is the principal storage form of phosphorus in many plant tissues, especially bran and seeds. Phytate is not digestible to humans or nonruminant animals, so it is not a source of either inositol or phosphate if eaten directly. Moreover, phytic acid chelates and thus makes unabsorbable certain important minor minerals such as zinc and iron, and to a lesser extent, also macro minerals such as calcium and magnesium; phytin refers specifically to the calcium or magnesium salt form of phytic acid.
