A fatty acid which has a chain length greater than C22. Very long-chain fatty acids which have a chain length greater than C27 are also known as ultra-long-chain fatty acids.

| lignoceric acid | A C24 straight-chain saturated fatty acid. | tetracosanoic acid |
| phthioic acid | A methyl-branched fatty acid that is tricosanoic acid substituted by a methyl group at positions 3, 13 and 19. | 3,13,19-trimethyltricosanoic acid |
| psyllium | | Psyllic acid |
| sq-23377 | A very long-chain fatty acid that is docosa-10,16-dienoic acid which is substituted by methyl groups at positions 4, 6, 8, 12, 14, 18 and 20, by hydroxy groups at positions 11, 19 and 21, and by a (2',5-dimethyloctahydro-2,2'-bifuran-5-yl)ethanol group at position 21. An ionophore produced by Streptomyces conglobatus, it is used in research to raise the intracellular level of Ca(2+) and as a research tool to understand Ca(2+) transport across biological membranes. | ionomycin |

| tricosanoic acid | A very long-chain fatty acid that is tricosane in which one of the methyl groups has been oxidised to the corresponding carboxylic acid. | tricosanoic acid |
