Three long-chain alkanes detected by Nasa’s Curiosity rover could be chemical biosignatures that point to a history of past ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

NASA’s Curiosity Martian rover finds organic-like, long-chain alkanes preserved in the planet’s mudstone Twelve years after ...

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical ...

Scientists analyzed a sample, which likely contained fatty acids, that transformed into alkanes during the heating process ...

The longest unbranched chain containing the functional group is the parent molecule, or simply the longest unbranched chain for alkanes. Remember that, the longest chain can go round a bend.
