linoleic acid

 [lin″o-le´ik]
an essential fatty acid that cannot be synthesized by animal tissues and must be obtained in the diet.

lin·o·le·ic ac·id

(lin'ō-lē'ik as'id), Do not confuse this word with linolenic acid.
9,12-Octadecadienoic acid; a doubly unsaturated 18-carbon fatty acid, occurring widely in plant glycerides, that is essential in nutrition in mammals.
Synonym(s): linolic acid
[L. linum, flax, + oleum, oil]

linoleic acid

(lĭn′ə-lē′ĭk)
n.
An unsaturated fatty acid, C18H32O2, that is considered essential to the human diet. It is an important component of drying oils, such as linseed oil.

linoleic acid

An essential 18-carbon fatty acid with two unsaturated bonds which derived from plant oils.

lin·o·le·ic ac·id

(lin'ō-lē'ik as'id) Do not confuse this word with linolenic acid.
Doubly unsaturated 18-carbon fatty acid, occurring widely in plant glycerides; essential in nutrition in mammals.
[L. linum, flax, + oleum, oil]

linoleic acid

The principle fatty acid in plant seed oils. An essential polyunsaturated fatty acid, interconvertible with LINOLENIC ACID and arachidonic acid and needed for cell membranes and the synthesis of PROSTAGLANDINS. It is plentiful in vegetable fats. Essential fatty acid dietary deficiency is rare.

linoleic acid

or

essential fatty acid

an unsaturated fatty acid that cannot be synthesized in the human body and is therefore described as ‘essential’. Deficiency of linoleic acid in the diet results in increased metabolic activity, failure in growth and even death.
