The role that fragmentation plays on the char particle history is incorporated into the model and the possible production of fine particulate through fragmentation is examined.

PN was able to nitrosate CA in highly acidic medium and excess CA to form S-nitrosocysteamine (CANO) in a 1:1 with the formation of one mole of CANO from one mole of ONOOH. In excess oxidant (PN) the following 1:2 stoichiometric ratio was obtained; ONOO- + 2CA → CA-CA + NO2- + H2O

Atherosclerosis is characterised by lipid deposition in the arterial wall and chronic low-grade inflammation. Leukocytes migrate to the area of injury and release the heme enzyme myeloperoxidase (MPO) into the extracellular matrix (ECM). This enzyme converts H2O2 to hypohalous acids (e.g.HOCl from Cl-, HOSCN from SCN-). There is considerable evidence that these oxidants, particularly HOCl, damage cells and the ECM, and contribute to cardiovascular disease. HOCl is a highly damaging oxidant, whereas HOSCN is less reactive and generates reversible modifications. The ECM contains multiple protein

Reactions of the free radical nitrogen monoxide (NO) with metal–oxygen species of metalloproteins are relevant to NO metabolism and detoxification.

This has led to the suggestion that the role of NO could be that of an antioxidant of oxoiron(IV) and oxoiron(IV) protein radicals to inhibit oxidative damage. In turn, the ferrylglobin-mediated oxidation of NO to nitrite may play a role in NO scavenging and detoxificati
