Auto-oxidation-reduction peroxide

This is an auto-oxidation-reduction reaction, the chlorine with oxidation number +i in chlorine dioxide being reduced and oxidized simultaneously to oxidation numbers -f 3 and -f 5. Pure sodium chlorite, NaClOg, can bfe made by passing chlorine dioxide into a solution of sodium peroxide ... 

The true metabolic role of HA per se (and not as mere precursor of other substances such as quinolinic acid and so on) is still awaiting a conclusive definition. However, HA toxicity seems to be related not to the compound itself, but rather to other substances, arising form its (auto)oxidation. As ever, one can speculate about the chemical nature of those species, therefore some evidence exists in favour of the profound involvement of reactive intermediates in dioxygen reduction, namely superoxide, peroxide and hydroxyl, whereas other indications suggest the participation of anthranilyl and/or HA quinoneimine in the toxicity mechanism.
