WebSep 7, 2024 · What type of iron is in hemoglobin? Heme iron, derived from hemoglobin and myoglobin of animal food sources (meat, seafood, poultry), is the most easily absorbable form (15% to 35%) and contributes 10% or more of our total absorbed iron. Non-heme iron is derived from plants and iron-fortified foods and is less well absorbed. WebAt the same time, it also says that only 0.347% of the whole molecule is iron (and says that only 4 iron atoms are in hemoglobin). By mass, yes there are plenty of other atoms in the molecule. Seeing as Hemoglobin is an incredibly complex molecule I would recommend naming it Molecule X and retrying the problem.
