(9Z,12E)-octadeca-9,12-dienoic acid

Description:

(9Z,12E)-octadeca-9,12-dienoic acid, commonly known as alpha-linolenic acid (ALA), is a polyunsaturated fatty acid belonging to the omega-3 family. It is characterized by its long carbon chain, consisting of 18 carbon atoms and two double bonds located at the 9th and 12th positions, with specific geometric configurations (cis and trans). ALA is an essential fatty acid, meaning it cannot be synthesized by the human body and must be obtained through diet, primarily from plant sources such as flaxseeds, chia seeds, and walnuts. This fatty acid plays a crucial role in human health, contributing to cardiovascular health, anti-inflammatory processes, and overall cellular function. ALA is also a precursor to other important omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). In terms of physical properties, ALA is typically a colorless to pale yellow liquid at room temperature and is soluble in organic solvents but less so in water. Its chemical structure and properties make it significant in both nutrition and biochemistry.

CAS: 2420-42-0

9(Z),12(E)-Octadecadienoic Acid (C18:2(9E,12Z); C18:2 n-6), an isomer of linoleic acid, is a type of ω-6 polyunsaturated fatty acid containing a trans double bond at the C9 position. It is identified as a minor component in milk fat and partially hydrogenated vegetable oils. The concentration of 9(Z),12(E)-Octadecadienoic Acid in rabbit meat increases following supplementation with heated sunflower seed oil, α-tocopherol acetate, and zinc.
