Linoleic acid

Linoleic acid is an organic compound fatty acid.

Linoleic acid is a polyunsaturated omega-6 fatty acid. 


It is virtually insoluble in water but soluble in many organic solvents.



It typically occurs in nature as a triglyceride, rather than as a free fatty acid.



It is one of two essential fatty acids for humans, who must obtain it through their diet.



Linoleic consumption is vital to proper health, as it is an essential fatty acid.



Linoleic acid is a precursor to arachidonic acid (AA).



Arachidonic acid is the precursor to some prostaglandins, leukotrienes, and thromboxane (TXA).



Linoleic acid is also converted by lipoxygenases, cyclooxygenases, cytochrome P450 enzymes, and non-enzymatic autoxidation mechanisms to mono-hydroxyl products, implicated in  physiology and pathology.



Linoleic acid is a component of quick-drying oil paints and varnishes.



Linoleic acid is a surfactant.



Has beneficial properties on the skin, with anti-inflammatory, acne reductive, skin-lightening and moisture retentive properties when applied topically on the skin.



LA is abundant in safflower, sunflower, corn, and comprises over half their composition by weight. 



It is present in medium quantities in soybean oils, sesame, and almonds.
