Ascorbate removes key precursors to oxidative damage by cell-free haemoglobin in vitro and in vivo

Haemoglobin initiates free radical chemistry. In particular, the interactions of peroxides with the ferric (met) species of haemoglobin generate two strong oxidants: ferryl iron and a protein-bound free radical. We have studied the endogenous defences to this reactive chemistry in a rabbit model fol...
