"WebOct 4, 2024 · Haemoglobin is a complex protein that contains a crucial iron atom. The iron is present as a 2+ cation, but the haeme ring that binds to the iron has a 2- charge, so overall there is no charge on the complex. The iron is still electrophilic, however, and it can bind an oxygen molecule. " - Structure of haemoglobin pdf
