Oleic acid is a monounsaturated omega-9 fatty acid found in various animal and vegetable sources. It has the formula C18H34O2 (or CH3(CH2)7CH=CH(CH2)7COOH).[2] The saturated form of this acid is stearic acid.

Oleic acid makes up 55-80% of olive oil, though there may be only 0.5-2.5% or so as actual free acid, and 15-20% of grape seed oil and Sea buckthorn oil.[3]

Reduction of oleic acid at the carboxyl end yields oleyl alcohol.

Oleic acid is emitted by the decaying corpses of a number of insects, including bees and Pogonomyrmex ants and triggers the instincts of living workers to remove the dead bodies from the hive. If a live bee[4] or ant[5] is daubed with oleic acid, it is dragged off as if it were dead.
