Oleic acid is a monounsaturated omega-9 fatty acid found in various animal and vegetable fats. It has the formula CH3(CH2)7CH=CH(CH2)7COOH. It is an odorless, colourless oil, although commercial samples may be yellowish. The trans isomer of oleic acid is called elaidic acid (hence the name elaidinization for a reaction that switches cis isomers to trans isomers). The term "oleic" means related to, or derived from, oil or olive.
