Investigation of nicotianamine and 2′ deoxymugineic acid as enhancers of iron bioavailability in caco-2 cells por Beasley, Jesse T., Hart, Jonathan J., Tako, Elad, Glahn, Raymond P., Johnson, Alexander A. T.

“…Nicotianamine (NA) is a low-molecular weight metal chelator in plants with high affinity for ferrous iron (Fe2+) and other divalent metal cations. In graminaceous plant species, NA serves as the biosynthetic precursor to 2′ deoxymugineic acid (DMA), a root-secreted mugineic acid family phytosiderophore that chelates ferric iron (Fe3+) in the rhizosphere for subsequent uptake by the plant. …”

Influence of Salt and Alkali on Ionic Equilibria in Submerged Soils por Pasricha, N.S., Ponnamperuma, F.N.

“…In spite of wide variations in pH, Eh, ionic strength, and the concentrations of Fe2+ and Mn2+ in the soil solutions, the values of the expressions, pE − pFe2+ + 3 pH, pE − 1.5 pFe2+ + 4 pH, pE + pH, and pH − 0.5 pMn2+ − 0.5 pCO2 were nearly equal to 17.9, 23.3, 7.3, and 4.1, respectively, indicating that even in the salt and alkali treated soils, the Fe(OH)3‐Fe2+ and Fe3(OH)8‐Fe2+ systems controlled the solubility of Fe2+ while the MnCO3‐H2O‐CO2 system regulated the solubility of Mn2+.…”
