A new study confirms directly what scientists previously knew only indirectly: The poisonous “rotten egg” gas hydrogen sulfide is generated by our body’s growing cells.
Hydrogen sulfide, or H2S, is normally toxic, but in small amounts it plays a role in cardiovascular health.
In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says chemist Alexander R. Lippert, Southern Methodist University, Dallas. The discovery allows researchers to observe the process through a microscope.
The researchers captured on video the successful chemical probe at work, Lippert said.
