Product Introduction

Description

Nitric oxide (NO) is a colorless toxic gas that is formed by the oxidation of nitrogen . It performs important chemical signaling functions in humans and other animals and has various applications in medicine . It is a serious air pollutant generated by automotive engines and thermal power plants.

Synthesis Analysis

NO is synthesized from arginine and O2 by NO synthase (NOS). Citrulline formed as a by-product of the NOS reaction can be recycled to arginine by argininosuccinate synthetase (AS) and argininosuccinate lyase (AL). Intracellular arginine availability is a rate-limiting factor in cellular NO production.

Molecular Structure Analysis

NO is a relatively unstable, diatomic molecule that possesses a free radical (i.e., an unpaired electron). The molecule can gain or lose one electron to form the ions NO− or NO+.

Chemical Reactions Analysis

NO is a reactive molecule that can undergo various chemical reactions. It reacts rapidly with oxygen to form nitrogen dioxide, NO2. It is also an intermediate compound formed during the oxidation of ammonia to nitric acid .

Physical And Chemical Properties Analysis

NO is a small, uncharged molecule that contains an unpaired electron, making it highly reactive. It is almost insoluble in water, but it dissolves rapidly in a slightly alkaline solution of sodium sulfite.
