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.
(9Z,11E,13E)-Octadeca-9,11,13-trienoic acid (α-eleostearic acid). An octadecatrienoic acid is a chemical compound with formula C 18 H 30 O 2, a polyunsaturated fatty acid whose molecule has an 18-carbon unbranched backbone 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 ...
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).
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.
Lipoxygenases (EC 1.13.11.-) (LOX) are a family of (non-heme) iron-containing enzymes, more specifically oxidative enzymes, most of which catalyze the dioxygenation of polyunsaturated fatty acids in lipids containing a cis,cis-1,4-pentadiene into cell signaling agents that serve diverse roles as autocrine signals that regulate the function of their parent cells, paracrine signals that regulate ...
15-lipoxygenase 1 (), while best known for converting the 20 carbon polyunsaturated fatty acid, arachidonic acid, into a series of 15-hydroxylated arachidonic acid metabolites (see 15-hydroxyicosatetraenoic acid), actually prefers as its substrate the 18 carbon polyunsaturated fatty acid, linoleic acid, over arachidonic acid, converting it to 13-hydroperoxy-9Z,11E-octadecadienoic acid (13-HpODE).
