Linoleic acid
Linoleic acid is a doubly unsaturated fatty acid, also known as an omega-6 fatty acid, occurring widely in plant glycosides. In this particular polyunsaturated fatty acid (PUFA), the first double bond is located between the sixth and seventh carbon atom from the methyl end of the fatty acid (n-6). Linoleic acid is an essential fatty acid in human nutrition because it cannot be synthesized by humans. It is used in the biosynthesis of prostaglandins (via arachidonic acid) and cell membranes (From Stedman, 26th ed). Linoleic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism. Linoleic acid (LA) is an organic compound with the formula HOOC(CH2)7CH=CHCH2CH=CH(CH2)4CH3. Both alkene groups (−CH=CH−) are cis. It is a fatty acid sometimes denoted 18:2 (n-6) or 18:2 cis-9,12. A linoleate is a salt or ester of this acid.[5] Linoleic acid is a polyunsaturated, omega-6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents.[2] It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid.[6] It is one of two essential fatty acids for humans, who must obtain it through their diet,[7] and the most essential, because the body uses it as a base to make the others. The word "linoleic" derives from Latin linum 'flax', and oleum 'oil', reflecting the fact that it was first isolated from linseed oil.
Bovinic acid
Bovinic acid is a conjugated linoleic acid, present in human adipose tissue; the amount of bovinic acid in humans is significantly related to milk fat intake. Conjugated linoleic acids (CLAs) are a group of naturally occurring fatty acids present mainly in fats from ruminants. Milk contains over 20 isomers of CLA but the predominant one is cis-9,trans-11-CLA (bovinic acid). Biomedical studies with animal models have shown that this isomer has anticarcinogenic and anti-atherogenic activities. Bovinic acid is produced as an intermediate in the rumen biohydrogenation of linoleic acid but not of linolenic acid. However, it is only a transient intermediate, and the major source of milk fat CLA is from endogenous synthesis (PMID: 10393134, 15736916).

Malvalic acid
Malvalic acid, also known as 2-octyl-1-cyclopropene-1-heptanoic acid or 8,9-methylen-8-heptadecensaeure, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, malvalic acid is considered to be a fatty acid lipid molecule. Malvalic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Malvalic acid can be found in peanut and roselle, which makes malvalic acid a potential biomarker for the consumption of these food products. Malvalic acid is a cyclopropenic fatty acid found in cottonseed oil. The cyclopropene ring is thought to be one of the causes of abnormalities that develop in animals that ingest cottonseed oil. This reactivity could be cause for concern depending on concentration. Hydrogenation of the oil destroys malvalic acid .

Dihomolinoleic acid is considered to be practically insoluble (in water) and a very weak acidic compound.

8-Isoprostane
8-isoprostane concentrations are elevated in asthma and increase with the clinical severity and during acute asthma episodes. Isoprostane is formed in the airways of asthmatic patients from peroxidation of poly-unsaturated fatty acids in cell membranes, the effect of reactive oxygen species resulting of the NADPH oxidase of eosinophils, neutrophils and alveolar macrophages, which produces superoxide anion which undergoes dismutation to H2O2. (PMID 16354413). 8-isoprostane is also elevated in Bronchopulmonary dysplasia, which remains an important cause of morbidity and mortality in extremely premature newborn infants receiving intensive care and is the most common contributing factor to severe respiratory morbidity and mortality in early childhood. (PMID 14980283). 8-Isoprostaglandin F(2a) is a marker of oxidative stress in the aqueous humour of patients with exfoliation syndrome (XFS) (PubMed ID 12598453). 8-isoprostane concentrations are elevated in asthma and increase with the clinical severity and during acute asthma episodes.

(9E,11E)-Octadecadienoic acid
Conjugated linoleic acid is an integral term for the mixture of positional and geometrical isomers of the octadecadienoic acids, whose two double-bonds are separated with one single-bond. The most common isomers are cis-9, trans-11, and trans-10, cis-12. Conjugated linoleic acid is present in the food namely in the red meat and dairy products which the contemporary dietary recommendations tend to limit. Those limitations should be compensated with dietary supplements. Much attention has focused on the therapeutic potential of conjugated linoleic acid. Initial animal studies associated conjugated linoleic acid with beneficial health properties, such as reducing the risk of cancer, diabetes, atherosclerosis, inflammation and obesity. More recent human conjugated linoleic acid supplementation studies have often shown conflicting and less convincing health benefits. The marked variation between studies may reflect the isomer-specific effect of the individual conjugated linoleic acid isomers, which can often have opposing effects. Detrimental effects have been observed in some studies, in particular after supplementation with the trans-10,cis-12 conjugated linoleic acid isomer. Diet composition may modulate CLA effects on body fat accumulation. As far as human studies are concerned, a specific dietary pattern has not been established. As a result differences among studies and also among subjects in the same study are likely. In rodents, the effects of CLA vary with genotype, suggesting that genetic predisposition to fat accumulation can play an important role in the effectiveness of CLA. Human volunteers with different body mass index have participated in the published studies and even in the same experiment. So, differences in lipid metabolism among subjects could help to explain the discrepancies observed in the literature. Age and maturity may also be crucial. (PMID: 17053429, 17217167, 17554969, 16477173). Conjugated linoleic acid (CLA) is a collective term for a mixture of positional and geometric isomers of linoleic acid (18:2) in which the two double bonds are conjugated. CLA has been suggested to have effects on human health, including effects on body composition, blood lipids, liver metabolism, insulin sensitivity and immune function, with mixed results.
(10E,12Z)-Octadecadienoic acid
Conjugated linoleic acid (CLA) is a collective term for a mixture of positional and geometric isomers of linoleic acid (18:2) in which the two double bonds are conjugated. CLA has been suggested to have effects on human health, including effects on body composition, blood lipids, liver metabolism, insulin sensitivity and immune function, with mixed results. Some reported data suggest that the effects of the substance may be isomer dependent and that cis-9,trans-11 and trans-10,cis-12 conjugated linoleic acids have opposing effects, the later (trans-10,cis-12 CLA) having a relative detrimental effect on blood lipids. (PMID 16477173). (10E,12Z)-Octadeca-10,12-dienoic acidactivates PPAR α and inhibits adipocyte differentiation[1].

Linoelaidic acid
Linoelaidic acid is an isomer of linoleic acid, or conjugated linoleic acid (CLA), a derivative of a fatty acid linoleic acid. Conjugated linoleic acid (CLA) isomers, a group of positional and geometric isomers of linoleic acid [18:2(n-6)], have been studied extensively due to their ability to modulate cancer, atherosclerosis, obesity, immune function and diabetes in a variety of experimental models. CLAs ability to modulate human obesity remains controversial because data from clinical trials using mixed isomers are conflicting. (PMID 10759137).
