7-Linolenic acid 6,9,12-octadecatrienoic

The major fatty acids present in plant-derived fatty substances are oleic acid (9-octadecenoic, C18 l), linoleic acid (9,12-octadecadienoic, C18 2) and the conjugated isomers thereof and linolenic acid (9,12,15-octadecatrienoic, C18 3) (Scheme 31.1). Their rates of oxygen absorption are 100 40 1, respectively, hence partial hydrogenation with consequent lowering of the iodine number would lead to a significant increase in oxidative stabihty, particularly when C18 3 is reduced. [Pg.273]

Important essential fatty acids in the diet are linoleic acid (cis,cis-9,12-octadecadienoic acid, 18 2d9,12) and a-linolenic acid (all-cis-9,12,15-octadecatrienoic acid 18 3d9,12,15). The numbering in this conventional system begins with the carboxyl group. The "short hand," for example 18 2d9,12, indicates 18 carbon atoms, with two double bonds located between carbon atoms 9 and 10 and 12 and 13. There is an alternative system of numbering in which fatty acids are numbered from the methyl (or a>) terminal. In this case, linoleic acid is designated a>-6,9-octadecadienoic acid (18 2ft)6), and a-linolenic acid is o>-3,6,9-octadecatrienoic acid (18 3ft)3). This serves to designate two unsaturated fatty acid families, the ft)6 and the a families. [Pg.428]

A double bond between two carbon atoms indicates the site, and possibly type, of hydrogen unsaturation. When double bonds are present, the suffix anoic is changed to enoic, dienoic, or trienoic to indicate the number of bonds. The location of the first carbon in the double bond is indicated by a number preceding the systemic name. Under International Union of Pure and Applied Chemistry (IUPAC) convention, stearic, oleic, linoleic, and linolenic acids are called octadecanoic, 9-octadecenoic, 9,12-octadecadienoic, and 9,12,15-octadecatrienoic acids, respectively. [Pg.1566]

Fatty acids with two or more conjugated double bonds are found in some plants and animals. In tissues of ruminant animals (and, hence, in meat and dairy products), fatty acids with conjugated diene system were detected as intermediates or by-products in the biohydrogenation of linoleic acid by microorganisms in the rumen. The main isomer, 9-cis, ll-fran -octadecadienoic acid, may account for up to 1% of the total fatty acids of milk fat. 9-cis, ll-fran5-15-cw-octadecatrienoic acid, derived from a-linolenic acid, is present in ruminant tissues only in trace levels. This fatty acid has been shown to have several medical properties, especially anti-cancer and anti-atherosclerosis effects. [Pg.944]

A mixture of 9S-HPODE and 13S-HPODE is obtained when soybean lipoxygenase reacts with linoleic acid at pH 6,4 [156]. Lipoxygenase of tomatoes [157] produces mainly 9S-10E,12Z-octadecadienoic acid (9S-HPODE, Scheme 4) from linoleic acid and 9S,10E,12Z,15Z-octadecatrienoic acid (9S-HPOTE, Scheme 5) from linolenic acid. [Pg.70]

The most important and widely distributed PEFAs are linoleic (d,s,m-9,12-octadecadienoic) and linolenic (cis,cis,cis-9,12,15-octadecatrienoic) acids. Linoleic acid, one of the nutritionally essential FAs, is the most abundant PEFA and is widely distributed in common vegetable oils such as soybean oil (50%), sunflower oil (65%), com oil (50%), and sesame oil (40%). Linolenic acid distributed in nature is a major acid of the highly unsaturated vegetable oils. Rich sources are linseed (45-50%) and perilla (65%) oils. [Pg.117]
