To elucidate the mechanism of the phosphorylation of myo-inositol in the process of phytate formation, feeding experiments of orthophosphate-^<32>P and myo-inositol-^3H in the ripening grains of rice and wheat were performed. It was found that 3'P and ^3H were incorporated into myo-inositol mono- and hexa-phosphates. The same results were obtained when a mixture of "cold" myo-inositol polyphosphates was administered to the grains before feeding phosphate-^<32>P. Based on these results it is concluded that phosphorylation of free myo-inositol in the formation of phytate does not take place in a stepwise fashion but may proceed through an unknown myo-inositol derivative.
