The product form on oxidation of iron
WebbIron from food comes in two forms: heme and non-heme. Heme is found only in animal flesh like meat, poultry, and seafood. Non-heme iron is found in plant foods like whole grains, nuts, seeds, legumes, and leafy greens. Non-heme iron is also found in animal flesh (as animals consume plant foods with non-heme iron) and fortified foods. WebbInitially, pyrite oxidation involves the adsorption of O 2 and water to the partly protonated pyrite surface by bonding to Fe 2+ (Fornasiero et al., 1994). Various iron oxyhydroxide intermediate products can form on the pyrite surface, depending on pH.
