Linoleic acid is a diunsaturated acid with two double bonds and 18 carbon atoms and is named from the diunsaturated hydrocarbon octadecadiene (Table 1.3). Octadecadien( e ) → octadecadien( oic ) acid → 9, 12-octadecadienoic acid
23 Σεπ 2005 · The kernel oils revealed essential fatty acids such as polyunsaturated (α-linolenic and linoleic acids) and monounsaturated fatty acids (palmitic, palmitoleic, and oleic acids).
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.
Definition. Linoleic acid (LA) is an 18-carbon, polyunsaturated fatty acid (PUFA), which contains two cis double bonds. Because mammals cannot introduce a double bond at carbon atoms beyond C-9 in the fatty acid chain, linoleic acid (18:2 cis -Δ 9,Δ 12) and linolenic acid (18:3 cis -Δ 9, Δ 12,Δ 15) are two essential fatty acids.
This symbol describes an acid such as linoleic with 18 carbon atoms (assumed to be straight-chain) and two unsaturated centres (assumed to be cis-olefinic). Since there are many isomeric compounds which could be represented by this symbol additional descriptors may be added thus: 18:2 (9,12), 18:2 (9c,12c), 18:2 (9Z,12Z), 18:2 (n-6)
One of the most well-studied conjugated fatty acids is conjugated linoleic acid (CLA) (Figure 1-3-2). CLA was first isolated as an anti-cancer agent from cooked meat. After-wards, discovery of its body-fat-reducing-effect made CLA be used for diet food. There can be many isomers of CLA with respect to the position and the configuration
