Hydrogen sulfide (H2S) has recently been added to the panel of small molecule signaling agents like NO and CO implicated in vasodilation and prevention of myocardial ischaemia-reperfusion injury. Although the biological mechanisms  by which H2S performs its function is still unclear, it may likely be due to reaction with Reactive Nitrogen Species like nitrite, GSNO, and nitrosyl hydride (HNO). This study describes attempts to characterize HNO produced from the reaction of H2S with GSNO or HNSO via secondary reactivity with deoxymyoglobin using kinetic analysis of UV-vis absorbances and proton NMR data.
