What prevents our cells being damaged due to overexposure to iron ions is a protein called lactoferrin, known for its ability to bind tightly to such ions. Researchers used a combined experimental and molecular dynamics simulation to study the changes in the structure of lactoferrin as it binds to iron ions.
