linoleic acid
lin·o·le·ic acid L0188600 (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.
[Greek linon, flax; see lī̆no- in Indo-European roots + oleic acid.]linoleic acid (ˌlɪnəʊˈliːɪk) n (Elements & Compounds) a colourless oily essential fatty acid found in many natural oils, such as linseed: used in the manufacture of soaps, emulsifiers, and driers. Formula: C18H32O2[C19: from Latin līnum flax + oleic acid; so named because it is found in linseed oil]lin′o•le′ic ac′id (ˈlɪn lˈi ɪk, ˌlɪn-, lɪˈnoʊ li ɪk) also li•no′lic ac′id (lɪˈnoʊ lɪk)
n. an unsaturated fatty acid, C18H32O2, occurring as a glyceride in drying oils, as in linseed oil.

TranslationsLinoleic Acid
linoleic acid[¦lin·e¦lē·ik ′as·əd] (biochemistry) C17H31COOH A yellow unsaturated fatty acid, boiling at 229°C (14 mmHg), occurring as a glyceride in drying oils; obtained from linseed, safflower, and tall oils; a principal fatty acid in plants, and considered essential in animal nutrition; used in medicine, feeds, paints, and margarine. Also known as linolic acid; 9,12-octadecadienoic acid. Linoleic Acid a monobasic carboxylic acid with two isolated double bonds, CH3(CH2)3 (CH2CH=CH)2(CH2)7COOH; a colorless oily liquid. Melting point, — 11°C; boiling point, 182°C (at 532 newtons per sq m, or 4 mm of mercury); density, 0.903 g/cm3 at 20°C. Together with arachidonic acid and linolenic acid, linoleic acid is an irreplaceable fatty acid, necessary for normal vital activity. These acids are ingested by humans and animals with food, mainly in the form of complex lipids (triglycerides and phosphatides). A substantial quantity of linoleic acid in triglyceride form (up to 40–60 percent) is known to occur in many vegetable oils and animal fats, such as soy, cottonseed, sunflower, linseed, and hemp oils and whale blubber. linoleic acid

[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.EncyclopediaSeelá nualinoleic acid
