Any fatty acid with one double or triple bond in the fatty acid chain and singly bonded carbon atoms in the rest of the chain. MUFAs have positive effects on the cardiovascular system, and in diabetes treatment.

| 10-nitro-oleic acid | A nitro fatty acid that is (9E)-octadec-9-enoic (elaidic) acid substituted by a nitro group at position 10. | (9E)-10-nitrooctadecenoic acid |
| 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 |
| 9,10,13-trihydroxy-11-octadecenoic acid | A TriHOME that is (11E)-octadec-11-enoic acid in which the three hydroxy substituents are located at positions 9, 10 and 13. | 9,10,13-TriHOME |
| citronellic acid | A monounsaturated fatty acid that is oct-6-enoic acid carrying methyl groups at positions 3 and 7. | citronellic acid |
| hydnocarpic acid | A cyclopentenyl fatty acid consisting of undecanoic acid having a cyclopent-2-enyl group at the 11-position. | hydnocarpic acid |
| malvalic acid | A long-chain cyclopropenyl fatty acid comprising 8-heptadecenoic acid having a cyclopropene ring arising from the linking of C-8 and C-9 by a methylene substituent. | malvalic acid |
| propiolic acid | A terminal acetylenic compound that is a 3-carbon, straight-chain, monounsaturated fatty acid having one acetylenic bond. | propynoic acid |
| senecioic acid | A methyl-branched fatty acid that is but-2-enoic acid bearing a methyl substituent at position 3. | 3-methylbut-2-enoic acid |
| sterculic acid | A long-chain, monounsaturated fatty acid composed of 9-octadecenoic acid having a 9,10-cyclopropenyl group. | sterculic acid |
| trans-3-methyl-2-hexenoic acid | A monounsaturated fatty acid that is (2E)-hexenoic acid in which the hydrogen at position 3 has been replaced by a methyl group. A malodourous component in the sweat of schizophrenics. | (2E)-3-methylhex-2-enoic acid |
