It belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons and therefore consist entirely of hydrogen atoms and saturated carbon atoms. Thus, octadecane is a hydrocarbon lipid molecule. Octadecane is an odorless white crystal or powder that is very hydrophobic, practically insoluble in water, and relatively neutral. Octadecane is an alkane taste. It has been detected in papaya, corianders, sunflowers, kohlrabis, and parsnips. This could make octadecane a potential biomarker for the consumption of these foods. Octadecane, in addition to other flavonoids, alyloids and sugars, extracted from the root of Trichosanthes dioica, exhibited antimicrobial activity against Proteus mirabilis¬†and Bacillus subtilis http://www.phytojournal.com/archives/?year=2016&vol=5&issue=5&part=F&ArticleId=985) CH3-[CH2]16-CH3 N-octadecane Oktadekan C18H38 254.4943 254.297351216 octadecane octadecane 593-45-3 CCCCCCCCCCCCCCCCCC InChI=1S/C18H38/c1-3-5-7-9-11-13-15-17-18-16-14-12-10-8-6-4-2/h3-18H2,1-2H3 RZJRJXONCZWCBN-UHFFFAOYSA-N belongs to the class of organic compounds known as alkanes.
