Occurrence, Distribution, Content, and Dietary Intake of Phytate

Abstract

PHYTATE (myo-inositol hexakisphosphate, InsP6) widely occurs in plantseeds and/or grains [1-4], roots and tubers [1,3,5,6], fruits and vegetables [3,5,6], nuts [3,5], pollen of various plant species [7-9], and organic soils [10,11]. The phytate fraction of organic soil contains a mixture of phosphorylated derivatives of myo-, chiro-, scyllo-, and neo-inositol [12]. Inositol phosphates with fewer than six phosphate groups, such as myo-inositol 1,3,4,5,6pentakisphosphate, have been isolated and identified from the nucleated erythrocytes of birds, turtles, and freshwater fish [13-17].
