Member	Definition	Role
17-octadecynoic acid	An acetylenic fatty acid that is octadecanoi acid (stearic acid) which has been doubly dehydrogenated at positions 17 and 18 to give the corresponding alkynoic acid.	octadec-17-ynoic acid
2-octynoic acid	An acetylenic fatty acid that is octanoic acid (caprylic acid) which has been doubly dehydrogenated at positions 2 and 3 to give the corresponding alkynoic acid. It is widely used in perfumes, lipstick, and many common food flavourings.	2-octynoic acid
5,8,11-eicosatriynoic acid	A C20 polyunsaturated fatty acid having three triple bonds in the 5-, 8- and 11-positions.	5,8,11-icosatriynoic acid
dicranin	A trienoic fatty acid, that is octadecanoic acid containing double bonds at positions 9, 12 and 15 and a triple bond at position 6. Isolated from Dicranum scoparium, it exhibits antibacterial activity and inhibitory activity against arachidonate 15-lipoxygenase.	(9Z,12Z,15Z)-octadeca-9,12,15-trien-6-ynoic acid
minquartynoic acid	A straight-chain, C18 polyunsaturated fatty acid having four conjugated C#C bonds at positions 9, 11, 13 and 15 as well as an (S)-hydroxy group at position 17.	minquartynoic acid
propiolic acid	A terminal acetylenic compound that is a 3-carbon, straight-chain, monounsaturated fatty acid having one acetylenic bond.	propynoic acid
