Bacteria and archaea Methanogenic archaea in the gut of this cow are responsible for some of the methane in Earth's atmosphere. Emily Lakdawalla. "Titan: Arizona in an Icebox?".

The carbon–hydrogen stretching mode gives a strong absorption between 2850 and 2960 cm −1, while the carbon–carbon stretching mode absorbs between 800 and 1300cm −1. The carbon–hydrogen bending modes depend on the nature of the group: methyl groups show bands at 1450cm −1 and 1375cm −1, while methylene groups show bands at 1465cm −1 and 1450cm −1. Carbon chains with more than four carbon atoms show a weak absorption at around 725cm −1. Po IUPAC metodu, imenovanje alkana je prilično jednostavno. Imena svih alkana završavaju na -an. Prefiks je baziran na broju atoma ugljika pojedinog alkana. a b c EA Baker (1982) Chemistry and morphology of plant epicuticular waxes. pp. 139-165.

Pojav imenujemo skeletna izomerija:Određivanje bočnih lanaca. Bočni lanci su ugljikovi lanci koji nisu dio glavnog lanca, nego se granaju s njega.

Pri standardnih pogojih so zato alkani od CH 4 do C 4H 10 plinasti, od C 5H 12 do C 17H 36 tekoči, od C 18H 38 pa trdni.

Naziv "neo-pentan" je iznimka - inače svi razgranati strukturni izomeri nekog alkana imaju prefiks -izo. The most important commercial sources for alkanes are natural gas and oil. [18] Natural gas contains primarily methane and ethane, with some propane and butane: oil is a mixture of liquid alkanes and other hydrocarbons. These hydrocarbons were formed when marine animals and plants (zooplankton and phytoplankton) died and sank to the bottom of ancient seas and were covered with sediments in an anoxic environment and converted over many millions of years at high temperatures and high pressure to their current form. Natural gas resulted thereby for example from the following reaction: Alkanes also play a role, if a minor role, in the biology of the three eukaryotic groups of organisms: fungi, plants, and animals. Some specialized yeasts, e.g., Candida tropicale, Pichia sp., Rhodotorula sp., can use alkanes as a source of carbon or energy. The fungus Amorphotheca resinae prefers the longer-chain alkanes in aviation fuel, and can cause serious problems for aircraft in tropical regions. [36]
