Biological functions of nitric oxide are roles that nitric oxide plays within biology.
Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of NO. In mammals including humans, nitric … 展开

In cells, two broad classes of reactions of nitric oxide involve the S-nitrosation of thiols and the nitrosylation of some metalloenzymes 展开

In plants, nitric oxide can be produced by any of four routes: (i) L-arginine-dependent nitric oxide synthase, (although the existence of animal NOS homologs in plants is debated), (ii) plasma membrane-bound nitrate reductase, (iii) mitochondrial electron transport chain, … 展开

Nitric oxide biosynthesis
Platelet-derived factors, shear stress, acetylcholine, and cytokines stimulate the production of NO by endothelial nitric oxide synthase (eNOS). eNOS synthesizes NO from the terminal guanidine 展开

Nitric oxide is generated by phagocytes (monocytes, macrophages, and neutrophils) as part of the human immune response. Phagocytes are armed … 展开

Nitric oxide dilates blood vessels, raising blood supply and lowering blood pressure. Conversely, it helps protect tissues from damage due to low blood supply. Also a neurotransmitter, … 展开

Blood-sucking insects exploit vasodilation induced by NO to ensure their blood meal. These insects include Cimex lectularius (bed bug) and … 展开
