Sulfides, thiols, disulfides, thioesters, thioketones, thioureas (2), sulfoxides and sulfonates (+4), and sulfones and sulfonamides (+6) exhibit various oxidation states, highlighting the versatile role of sulfur in biochemistry (2)
in fact, the release of glutathione takes place through a pH dependent release kinetics, triggered following exposure of the HAP delivery system with the weakly acidic pH present in the skin (mechanism schematized in figure 1)
