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). The saturated form of this acid is stearic acid. It is used in Lorenzo's oil.
Oleic acid comprises 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.
Reduction of oleic acid yields oleyl alcohol.
