linolsäure

Linolsäure is an omega-6 fatty acid, meaning it has a double bond six carbons away from the methyl end of its fatty acid chain. It is a polyunsaturated fatty acid and is considered an essential fatty acid, as the human body cannot synthesize it and must obtain it through diet. Linolsäure is the most abundant polyunsaturated fatty acid in vegetable oils and is found in many common foods.

Chemically, linolsäure is a carboxylic acid with an 18-carbon chain and two cis-double bonds at positions 9 and 12. Its systematic name is cis,cis-9,12-octadecadienoic acid. It is a colorless liquid at room temperature.

Linolsäure plays several important roles in the body. It is a precursor to arachidonic acid, which is involved in various physiological processes including inflammation, blood clotting, and cell signaling. Linolsäure is also a component of cell membranes and contributes to skin barrier function.

Dietary sources of linolsäure include sunflower oil, safflower oil, soybean oil, corn oil, and nuts like walnuts and pecans. While essential, excessive intake of linolsäure relative to omega-3 fatty acids has been a subject of research regarding its potential impact on health. The balance between omega-6 and omega-3 fatty acids in the diet is generally considered important for overall well-being.
