Oleic acid is a mono-unsaturated omega-9 fatty acid found in various animal and vegetable sources. It has the formula CH3(CH2)7CH=CH(CH2)7COOH.[2] The trans-isomer of oleic acid is called elaidic acid.

Oleic acid may hinder the progression of ALD, or adrenoleukodystrophy, a fatal disease that affects the brain and adrenal glands.

Oleic acid may help boost memory.

Oleic and monounsaturated fatty acid levels in the membranes of red blood cells have been associated with increased risk of breast cancer. Oleic acid may be responsible for the hypotensive (blood pressure reducing) effects of olive oil. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
