Definition
Myristoleic acid is a tetradecenoic acid in which the double bond is at the 9-10 position and has Z configuration. Myristoleic acid has been isolated from Serenoa repens and has cytotoxic and apoptosis-inducing effects. It has a role as an apoptosis inducer, a plant metabolite and an EC 3.1.1.1 (carboxylesterase) inhibitor. It is a long-chain fatty acid and a tetradecenoic acid. It is a conjugate acid of a myristoleate.
