  2. α-Linolenic acid - Wikipedia

    en.wikipedia.org/wiki/Α-Linolenic_acid

    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 .

  3. Essential fatty acid - Wikipedia

    en.wikipedia.org/wiki/Essential_fatty_acid

    Essential fatty acids, or EFAs, are fatty acids that are required by humans and other animals for normal physiological function that cannot be synthesized in the body. [1] [2] ⁠ As they are not synthesized in the body, the essential fatty acids – alpha-linolenic acid (ALA) and linoleic acid – must be obtained from food or from a dietary supplement.

  4. Omega-3 fatty acid - Wikipedia

    en.wikipedia.org/wiki/Omega-3_fatty_acid

    Chemical structure of eicosapentaenoic acid (EPA) Chemical structure of docosahexaenoic acid (DHA) An omega−3 fatty acid is a fatty acid with multiple double bonds, where the first double bond is between the third and fourth carbon atoms from the end of the carbon atom chain. "Short-chain" omega−3 fatty acids have a chain of 18 carbon atoms ...

    α-Linolenic acid (alpha-linolenic's) has 18 carbons, is found in linseed oil and drying oil, and is a 9,12,15-tri-unsaturated fatty acid. C 17 H 29 CO 2 H, IUPAC organization name (9 Z , 12 Z , 15 Z )-octadeca-9,12,15-trienoic acid, numerical representation 18:3 (9,12,15), n-3, molecular weight 278.43, melting point −11 °C, specific gravity ...

  6. Polyunsaturated fat - Wikipedia

    en.wikipedia.org/wiki/Polyunsaturated_fat

    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. The process is complicated by the sensitive nature of PUFAs, leading to side reactions and colorization.

  7. List of omega-3 fatty acids - Wikipedia

    en.wikipedia.org/wiki/List_of_omega-3_fatty_acids

    Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).

    Fatty acid breakdown. There is a wide variety of fatty acids found in nature. Two classes of fatty acids are considered essential, the omega-3 and omega-6 fatty acids. Essential fatty acids are necessary for humans but cannot be synthesized by the body and must therefore be obtained from food.
