A polyunsaturated fatty acid (with one more double bond than linoleic acid) present as a glyceride in linseed and other oils and essential in the human diet.
- ‘Since plants are capable of synthesizing linoleic and linolenic acid humans can acquire these fats by consuming a variety of plants or else by eating the meat of animals that have consumed these plant fats.’
- ‘We must point out that two fatty acids are as important in the human diet as vitamins: linoleic and gamma-linolenic acid.’
- ‘Manufacturers hydrogenate soybean oil to reduce its content of unsaturated fatty acids, particularly linolenic acid, the primary culprit responsible for causing food to become stale or rancid.’
- ‘Linoleic and linolenic acid are essential fatty acids that are needed to make critical compounds in the body.’
- ‘Sources of the essential fatty acid linolenic acid are soybean oil, canola oil, walnuts and flaxseed.’
Late 19th century: from German Linolensaüre, from Linolsaüre linoleic acid with the insertion of -en- (from -ene).
