10-Undecynoic acid (10- UDYA, UDY) is an acetylenic fatty acid. It is reported as highly selective irreversible inhibitor of hepatic ω- and ω-1-lauric acid hydroxylases. Enzyme catalyzed esterification of 10-undecynoic acid has been reported. UDY has been reported to be synthesized by the dehydrobromination of 10-undecenoic acid.
