In the atmosphere of the earth,many gases including nitrogen (N2),oxygen (O2),and carbon dioxide (CO2) naturally exist to support universal lives.Interestingly,in mammals and plants,some gases are produced endogenously and are known to play essential roles in sustaining life\'s processes.Nitric oxide (NO),carbon monoxide (CO),and hydrogen sulfide (H2S) are such molecules.The trinity of such gaseous molecules is sometimes referred to as gasotransmitters,with some debate.
