Document Abstract:
Nitric oxide (NO∑ ) and nitrogen dioxide (NO2.) are reactive nitrogen species which are radicals, ie they have an unpaired electron, usually associated with the nitrogen atom1. NO∑ is not very reactive with other non-radicals, but reacts rapidly with other radicals eg reaction with O2∑ - to form the non-radical peroxynitrite ONOO- (a reactive nitrogen or oxygen species)1. NO∑ is a colourless gas which diffuses easily within and between body cells, where it has important physiological actions1. NO∑ ís ability to scavenge ONOO- and other damaging radicals may make it an important antioxidant in vivo2.
