'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).^[1] The saturated form of this acid is stearic acid. It is used in Lorenzo's oil.
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.^[2]
Reduction of oleic acid at the carboxyl end yields oleyl alcohol.
Oleic acid is emitted by decaying bee corpses and triggers the instincts of living bees to remove the dead bodies from the hive. If a drop of oleic acid were to be added to a live bee, it would be dragged off, as if it were dead.
