Peroxynitrite is a short-lived and reactive biological oxidant formed from the diffusion-
controlled reaction of the free radicals superoxide (O2•–) and nitric oxide (• NO). In this …

The free radical nitric oxide (· NO) is a key mediator in different physiological processes such
as vasodilation, neurotransmission, inflammation, and cellular immune responses, and thus …

It has long been recognized that energy metabolism is linked to the production of reactive
oxygen species (ROS) and critical enzymes allied to metabolic pathways can be affected by …

Nitric oxide (NO) is a free radical acting as a cellular signaling molecule in many different
biochemical processes. NO is synthesized from l-arginine through the action of the nitric …
