Reactive sulfur species

Reactive sulfur species (RSS) are molecular forms containing sulfur that are chemically active and can interact with biological systems. They include substances like hydrogen sulfide (H₂S), persulfides, and thiosulfates. RSS play roles in cell signaling, regulation of oxidative stress, and maintaining sulfur balance in the body. While essential in small amounts for health, their reactive nature means that imbalances can contribute to disease processes or cellular damage. Understanding RSS helps researchers explore their functions in physiology and their implications in conditions such as inflammation and aging.
