Possible Interaction: Nitrogen and Iron, Dietary

“In the former case, the symmetry of the iron ligand combination is restrained to have at most a small departure from Dlh or tetragonal symmetry by the four pyrrole nitrogen atoms of the porphyrin.”

“ Nitrogen addition decreased plant community-level biomass weighted (hereafter referred to as community-level) Fe concentration but increased Mn concentration, with a greater effect under (NH4)2SO4 addition.”

“Concentrations of flour proteins (albumins/globulins, gliadins, and glutenins) and key minerals iron , zinc, and sulfur), and baking quality (loaf volume) were markedly increased by increasing nitrogen levels and varied between years.”

“Science, this issue p. 356 Multiple bonds to nitrogen can stabilize iron in an unusually high oxidation state.”

“Here, the effect of a coordination environment induced by nitrogen (N) atoms coordinated with iron on the kinetic and thermodynamic stabilities of single-atom iron catalysts supported with carbon-based substrates (FeSA/CS) was investigated by density functional theory (DFT) calculations.”

“ Nitrogen addition enhanced the uptake of N, P, S, K, Mn, Cu and Zn by plants, while inhibited plant Fe uptake, but with no effect on the uptake of Ca or Mg.”

“… nitrogen (N) addition resulted in surface soil acidification and decreased acid buffering capacity, increased … (C), N, phosphorus (P), sulfur (S) and DTPA-extractable iron ( Fe ), manganese (Mn), and copper (Cu) contents, depleted the sum of base cations …), potassium (K) and sodium (Na), decreased the diversity of soil microbial community.”

“However, in all constructed wetlands iron plays important role in removal of organics, phosphorus and does have an impact on transformation of nitrogen and sulphur.”

“The good electrochemical properties of the as-prepared NSC-Fe materials could be attributed to the ultrathin graphene-like nanosheets structure and synergistic effects from codoping of iron and nitrogen.”

“Additionally, Fe electrode could increase sludge concentration, particle size, and enzyme activities related to nitrogen removal.”

“The removal efficiencies of total nitrogen rose from 1.83% to 93.3% probably because of autotrophic denitrification using electron donors produced by the corrosion of iron , as well as the favorable conditions for anammox due to iron ions.”
