Myristoleic acid is a long chain fatty acid and tetradecenoic acid. Myristoleic acid also known as 9-tetradecenoic acid is an omega-5 fatty acid and a conjugate of myristeolate. It is biosynthesized from myristic acid by enzyme stearoyl-CoA desaturase-1 but is considered to be rare in nature. The major source of Myristoleic acid is seed oil from plants belonging to family Myristicaceae which comprises about 30 percent of oil in some species. It is a constituent of Saw palmetto or Serenoa and appears to have activity against LNCaP prostate-cancer cells. It also consists of 1.89% of fats from fruit of species Durio graveolens. This acid is isolated from Serenoa repens and possess cytotoxic and apoptosis inducing effects. It plays a role of apoptosis inducer and a plant metabolite.
