Eicosenoic acid has 20 carbons, is found in a wide variety of plant oils, and is a cis-11-mono-unsaturated fatty acid. C 19 H 37 CO 2 H, IUPAC organization name ( Z )-icos-11-enoic acid, numerical representation 20:1 (11), n-9, molecular weight 310.51.
11-Eicosenoic acid, also called gondoic acid, is a monounsaturated omega-9 fatty acid found in a variety of plant oils and nuts; in particular jojoba oil. [2] It is one of a number of eicosenoic acids .
The terms "jojoba oil" and "jojoba wax" are often used interchangeably because the wax visually appears to be a mobile oil, but as a wax it is composed almost entirely (~97%) of mono-esters of long-chain fatty acids and alcohols (isopropyl jojobate), accompanied by only a tiny fraction of triglyceride esters. This composition accounts for its ...
Eicosenoic acid may refer to one of three closely related chemical compounds: 9-Eicosenoic acid (gadoleic acid), an omega-11 fatty acid (20:1ω11) 11-Eicosenoic acid (gondoic acid), an omega-9 fatty acid (20:1ω9) 13-Eicosenoic acid (paullinic acid), an omega-7 fatty acid (20:1ω7)
In chemical structure, EPA is a carboxylic acid with a 20-carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end. EPA is a polyunsaturated fatty acid (PUFA) that acts as a precursor for prostaglandin-3 (which inhibits platelet aggregation ), thromboxane-3 , and leukotriene-5 eicosanoids .
Erucic acid (22:1, n−9), which is found in rapeseed, wallflower seed, and mustard seed. Rapeseed with high erucic acid content is grown for commercial use in paintings and coatings as a drying oil. Canola oil comes from a cultivar of the rapeseed plant that has been bred, or in some cases genetically modified, to contain very little erucic acid.
Dihomo-gamma-linolenic acid (DGLA), i.e. 8Z,11Z,14Z-eicosatrienoic acid is an ω−6 fatty acid with three cis double bonds, each located between carbons 8-9, 11-12, and 14-15. Mead acid, i.e. 5Z,8Z,11Z-eicosatrienoic acid, is an ω−9 fatty acid containing three cis double bonds, each located between carbons 5-6, 8-9, and 11-12.
Enoyl-CoA-(∆) isomerase (EC 5.3.3.8, also known as dodecenoyl-CoA-(∆) isomerase, 3,2-trans-enoyl-CoA isomerase, ∆3(cis),∆2(trans)-enoyl-CoA isomerase, or acetylene-allene isomerase, [1] is an enzyme that catalyzes the conversion of cis- or trans-double bonds of coenzyme A (CoA) bound fatty acids at gamma-carbon (position 3) to trans double bonds at beta-carbon (position 2) as below:
