(fī'tik as'id),
The hexakisphosphoric ester of myo-inositol; the mixed salt with magnesium and calcium is phytin.

phytic acid

/phy·tic ac·id/ (fi´tik) the hexaphosphoric acid ester of inositol, found in many plants and microorganisms and in animal tissues.

phytic acid

(fī′tĭk)
n.
An antioxidant compound, C6H18O24P6, found abundantly in seeds and the bran of grain, that is the principal storage form of phosphorus in plants. Phytic acid is a strong chelator of calcium, zinc, and other minerals, and diets based on foods high in phytic acid, such as unrefined flour, can cause mineral deficiencies unless it is broken down by the sprouting of the seeds or by fermentation. Also called inositol hexakisphosphate.

phytic acid (fī´tik),

n a component of some high-fiber foods, including many cereal grains that may, in excessive amounts, cause constipation or interfere with the body's ability to absorb minerals.

phytic acid

used synonymously with phytate. See also phytin.
