Sulfane sulfur, which is sulfur in the thiosulfoxide form (represented as S 0), has been found to have remarkable regulatory functions in biological systems. The following review briefly outlines the unveiling of these functions of sulfane sulfur, its unique nature, and its biogeneration.

Hydrogen sulfide is a chemical compound with the formula H 2 S. It is a colorless chalcogen-hydride gas, and is toxic, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11] .

2019年12月28日 · Sulfane sulfur is a divalent sulfur atom bonded to another sulfur which is very reactive and labile. Compounds containing this reactive sulfur include persulfides, polysulfides, thiosulfate, thiosulfinates, polythionates, and elemental sulfur.

2024年4月1日 · The total amount of sulfane sulfur present in various forms can be measured using various methods after treatment with a reducing agent and its conversion into free sulfide ions. When determining total sulfane sulfur, it is essential to distinguish it from acid-labile sulfur.

2019年4月1日 · In this review, we focus on basic properties of simple RSS, highlight recent insights into the interconnectivity of RSS with reactive nitrogen species, and discuss recent advances in methods for RSS detection and measurement.

Hydrogen sulfide (H2S) functions in many physiological processes, including relaxation of vascular smooth muscles, mediation of neurotransmission, inhibition of insulin signaling, and regulation of inflammation. On the other hand, sulfane sulfur, ...

Both reactive sulfur spe-cies (H2S and sulfane sulfur) always coexist in biological systems. This review is focused on new findings in the field of sulfane sulfur’s biological role, and disruption of its level in some patho/physiological conditions. A few sulfane sulfur donors with potential applications are pre-sented.

2019年8月22日 · Sulfane sulfur has been recognized as a common cellular component, participating in regulating enzyme activities and signaling pathways. However, the quantification of total sulfane sulfur in biological samples is still a challenge. Here, we developed a method to address the need.

1987年1月1日 · The term, “sulfane,” designates sulfur atoms that are bonded covalently in chains only to other sulfur atoms. Sulfane atoms are somewhat unstable, readily oxidizing in air, reducing with thiols, and decomposing slowly in dilute acid to release free sulfur.

2012年11月15日 · This is a true sulfuration reaction because it can be considered to be the summation of two reactions: the reaction of H 2 S with oxygen to give rise to sulfane sulfur; and the incorporation...
