Linoleic acid has 18 carbons, is contained in many vegetable oils, particularly semi-drying oils, and is a cis-9-cis-12-di-unsaturated fatty acid. C 17 H 31 CO 2 H, IUPAC organization name (9Z, 12Z)-octadeca-9,12-dienoic acid, numerical representation 18:2 (9,12), n-6, molecular weight 280.45, melting point −5 °C, specific gravity 0.902. CAS ...
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.
Conjugated linoleic acid is both a trans fatty acid and a cis fatty acid. The cis bond causes a lower melting point and, ostensibly, also the observed beneficial health effects. Unlike other trans fatty acids, it may have beneficial effects on human health. [6]
α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid. ALA is found in many seeds and oils, including flaxseed , walnuts , chia , hemp , and many common vegetable oils .
For example, linoleic acid is designated "cis-Δ 9, cis-Δ 12 octadecadienoic acid". This nomenclature has the advantage of being less verbose than systematic nomenclature, but is no more technically clear or descriptive. [citation needed] n−x (or ω−x) n−3 (or ω−3)
Melting point: 28–29 °C ... Linolelaidic acid is an omega-6 trans fatty acid (TFA) and is a cis–trans isomer of linoleic acid.
For instance, the rumenic acid (cis-9, trans-11) is a conjugated trans fatty acid. Studies have suggested that conjugated linoleic acids, an isomer of conjugated fatty acids, can modulate inflammatory responses in the body. [6] However, CLA’s anti-inflammatory properties correlate to isomer dependence. [7]
Desaturases convert oleic acid into linoleic acid the precursor to alpha-linolenic acid, gamma-linolenic acid and dihomo-gamma-linolenic acid. [ 6 ] Industrial PUFAs are generally obtained by hydrolysis of fats that contain PUFAs.
