Reactive nitrogen species are produced from immune cell activation and can form peroxy nitrite.

“reactive nitrogen species and this is these are produced from immune Cell Activation such as macras which are activated in response to inflammatory cyto kindes that are produced when there's some sort of infection like a bacterial infection in the body these macrophases then produce nitrogen oxide and this nitrogen oxide reacts with super oxide which is a byproduct of mitochondrial metab metabolism to produce something called peroxy nitrite which is a very potent reactive nitrogen species that damages the cell”
