S-nitrosothiol

S-nitrosothiol

A type of organic sulfur-containing nitrite; can transport nitric oxide through the body by binding to the sulfur group.

It involves various NO-derivatives, such as NO radical, nitroxyl anion (NO-), peroxynitrite (ONOO-), and S-nitrosothiols (SNOs).
Other manuscripts in the JDD special section include a preclinical study using a murine multithermal burn model which found that N-acetylcysteine S-nitrosothiol nanoparticles prevent wound expansion and accelerate burn closure, and a practical, systematic approach to using wound dressings for the wound care novice.
This S-nitrosothiol exerts actions like that of endothelium-derived relaxing factor which leads to improved microcirculation through vasodilatation and antiplatelet aggregation effects [13, 14].
In man, the enzyme that produces nitric oxide (NO) from L-arginine is called nitric-oxide synthase The vasodilator gas, nitric oxide, is carried by hemoglobin in the form of S-nitrosothiol (SNO) (see Figure 1 online).

S-Nitrosothiols (RSNOs), including nitrosoglutathione (GSNO), nitrosocysteine, and nitroso-albumin, exist in fresh blood and are formed from the reaction of the corresponding thiols with oxidation intermediates of nitric oxide (NO) produced by endothelial (EC) and other cells (1).
Hemoglobin scavenges nitric oxide through the high-affinity ferrous sites on heme to form S-nitrosothiol (with an affinity to nitric oxide 8,000 times that of their affinity for oxygen) (33) by binding at b 93 cysteine residue on the globin chain.

Recent evidence from the US researchers indicated that a family of nitrous oxide-carrying molecules called S-nitrosothiols (SNOs) might be necessary for nitric oxide to function throughout the body.
Now, Benjamin Gaston of the University of Virginia School of Medicine in Charlottesville and his colleagues find that oxygen-poor blood produces NO-derived compounds called S-nitrosothiols, or SNOs.
