In recent years, researchers have developed a number of small-molecule donors that efficiently release RSSH in response to various stimuli, including pH, thiols, reactive oxygen species, enzymes, and light. These RSSH donors have provided researchers with chemical tools to uncover the potential function and role of RSSH as physiological signaling and\/or protecting agents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Critical Issues:<\/jats:title>\n                    <jats:p>\n                      Because RSSH, hydrogen sulfide (H\n                      <jats:sub>2<\/jats:sub>\n                      S), and higher order polysulfides are related to each other and can be present simultaneously in biological systems, distinguishing among the activities due to each of these species is difficult.
