Ethanolamine oleate is a salt of ethanolamine, a basic substance, and oleic acid. It is marketed under a trade name of Ethamoline as a sclerotic agent for the treatment of patients with esophageal varices that have recently bled, to prevent rebleeding. In vitro studies revealed that ethanolamine oleate inhibits fibrin clot formation because of the Ca2+-chelating ability of its constituent ethanolamine. Nevertheless, from in vivo studies it was suggested that intravascular injection of ethamoline activates the local coagulation system. The activation may be accelerated by an acute inflammatory process provoked by oleate, which is supported by such clinical manifestations as mild fever, retrosternal pain leukocytosis and an increase in plasma fibrinogen level.

Elaidic acid is the 9-trans isomer of oleic acid. It is a monounsaturated trans-fatty acid, which can be found in partially hydrogenated cooking oils. It was revealed, that elaidic acid inhibits HHT and HETE formation in human platelets incubated with arachidonic acid. Also was shown, that trans oleic acid increased plasma CETP activity, which increases low-density lipoprotein (LDL) cholesterol and decreases high-density lipoprotein (HDL).

Monoethanolamine is both a primary amine and a primary alcohol. It is an olamine derivative. Monoethanolamine occurs in every cell in the human body as the head group of Phosphatidylethanolamine. Monoethanolamine is a component of glycosylphosphatidylinositol-anchored proteins, which are essential for viability. Other sources of monoethanolamine or phosphoethanolamine in the human body are the degradation of sphingosine phosphate by sphingosine phosphate lyase and the degradation of the endocannabinoid anandamide by the fatty acid amine hydrolase. Monoethanolamine stimulates the rapid growth of mammalian cells in culture. Monoethanolamine has a cardioprotective role against ischemia/reperfusion injury via activation of the transcription factor STAT-3. Monoethanolamine is a chemical intermediate in the manufacture of cosmetics, surface-active agents, emulsifiers, pharmaceuticals, and plasticizing agents.
