Linolelaidic acid, (9E,12E)-9,12-octadecadienoic acid; Rumenic acid, (9Z,11E)-9,11-octadecadienoic acid This page was last edited on 4 January 2021 ...
Linoleic acid (LA) is an organic compound with the formula HOOC(CH 2) 7 CH=CHCH 2 CH=CH(CH 2) 4 CH 3. 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.
The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is a regioisomer of gamma-linolenic acid (GLA), an 18:3 (n−6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds).
9-Hydroxyoctadecadienoic acid (or 9-HODE) has been used in the literature to designate either or both of two stereoisomer metabolites of the essential fatty acid, linoleic acid: 9(S)-hydroxy-10(E),12(Z)-octadecadienoic acid (9(S)-HODE) and 9(R)-hydroxy-10(E),12(Z)-octadecadienoic acid (9(R)-HODE); these two metabolites differ in having their hydroxy residues in the S or R configurations ...
(9Z,11E,13E,15Z)-Octadeca-9,11,13,15-tetraenoic acid (α-parinaric acid) An octadecatetraenoic acid is a chemical compound with formula C 18 H 28 O 2, a polyunsaturated fatty acid whose molecule has an 18-carbon unbranched backbone with four double bonds. [1]
Linolelaidic acid is an omega-6 trans fatty acid (TFA) and is a cis–trans isomer of linoleic acid.It is found in partially hydrogenated vegetable oils. It is a white (or colourless) viscous liquid.
The positions are x+2 and x+y+4 for the first type (21 possibilities), and r+2 and r+3 for the second type (7 possibilities). The systematic name of the acid is formed by prefixing the positions of the double bonds to "decadienoic" or inserting them before the "dienoic" suffix.
