WebNov 7, 2024 · Signaling by H2S is proposed to occur via persulfidation, a posttranslational modification of cysteine residues (RSH) to persulfides (RSSH). Persulfidation provides a framework for understanding the physiological and pharmacological effects of H2S. Due to the inherent instability of persulfides, their chemistry is understudied. In this review, we … WebHydrogen sulfide (H2S) is a product of the thermal conversion of decayed organic matter. H2S is a toxic, flammable, and colorless gas and is a naturally occurring component of natural gas in some areas. Hydrogen sulfide is the predominant impurity in natural gas. Natural gas is classified as sour when H2S is present in amounts greater than 4 ppm.
