By drilling into Martian mudstone, the rover was able to identify thiophene, 2- and 3-methylthiophenes, methanethiol and dimethylsulfide that are all also present in Earth mudstone.
Methyl mercaptan, also known as methanethiol, is mainly used to produce methionine in industrial quantities as a dietary component in poultry and animal feed.
The moderate compounds, accounting for 1.26% to 25.9% of the total volatile compounds, included 2-methyl butanal, hexanal, and methanethiol. The minor compounds, accounting for 0.01% to 8.5% of the total volatile compounds, included propanal, butanal, 3-methyl butanal, pentanal, heptanal, benzaldehyde, octanal, nonanal, butane, carbon disulfide, 2-butene, n-pentane, hexane, heptane, octane, ethylacetate, 2-butanone, 2,3-butanedione, 3-hydroxy-2-butanone, 2-heptanone, 2,3-octanedione, dimethyl sulfide, ethanol, isopropyl alcohol, 1-pentanol, and 1,3,5-cycloheptatriene.
That may be because many of the compounds, such as thiophene, methanethiol and dimethyl sulphide, had sulphur atoms in their molecular structure -- which would strengthen the relatively fragile organic molecules, allowing them to survive the radiation bombarding the planet's surface for so long.
A French-built instrument revealed "several organic molecules and volatiles reminiscent of organic-rich sedimentary rock found on Earth, including: thiophene, 2- and 3-methylthiophenes, methanethiol, and dimethylsulfide," said the Science report.
They found these people produced a lot of sulphur compounds in their breath, especially methanethiol, which has an unpleasant boiled cabbage smell.
Because natural gas is colourless and odourless, companies often add Mercaptan or methanethiol, which has a pungent smell likened to rotten eggs, to make it easier to detect.

On November 15, 2014, a methanethiol leakage accident occurred at an American DuPont factory, which was located in the southeastern Houston area, causing 4 casualties, injuring 1 person, and affecting many surrounding residents.
Conversely, there are five ways of removing [H.sub.2]S in the organism: by its conversion into thiocyanate via rhodanese; by its transformation into sulphurous proteins; through thiol molecules; by converting haemoglobin into sulfhaemoglobin; and by its transformation into methanethiol.
This microorganism is isolated from freshwater sediment and obligately methylotrophic methanogen since it utilizes only methanol, methylamines, methanethiol, and dimethyl sulfide [26].
