We believe the endogenous form of iron in wheat bran is monoferric phytate. The differential extractability from bran of monoferric phytate versus the bulk of the phytate and the comparable MOssbauer parameters of the iron in synthetic mono-...

First, when Mossbauer spectra were compared between seeds and bran of wheat grown on hydroponic media enriched in 57pe and synthetic iron phytates (8), the spectra of the seeds and dissected bran (Figure 2) are very similar to the spectrum of solid monoferric phytate. The spectral parameters, quadrupole splitting and isomer shift (Table I), of wheat seeds and bran are identical with those of solid monoferric phytate all are within the range of those found with high-spin ferric compounds. 

The parameters indicate that the same iron configuration exists in the wheat seeds and bran and in the monoferric solid. The Mbssbauer measurements revealed differences between diferric and monoferric phytate (8).
