Abstract

In only the last 20 years, Nitric oxide (NO, nitrogen monoxide), one of the smallest and simplest molecules in Nature, has been found to be involved in an astounding number of mammalian physiological and pathophysiological phenomena. The importance of NO as a messenger molecule in the cardiovascular system was recognized in 1998 by the awarding of the Nobel Prize in Physiology or Medicine and over 70000 papers have appeared involving NO in biology. The simplicity of its chemical structure stands in stark contrast to the complexity of its biological actions, including its “Janus-faced” character as both beneficial and detrimental. This chapter is an overview of the history of this discovery, the fundamental chemistry of NO and its derivatives in the biological environment, and the multiple biological actions of NO.
