Fluorooleic Acid
Fluorooleic acid is a naturally occurring, unsaturated, and fluorinated fatty acid. The Delta notation is 18-F-18:1-delta-9c. Natural occurrence Fluoroleic acid, along with some other ω-fluoro-substituted fatty acids, occurs at about 10–20% in the seed oil of ''Dichapetalum toxicarium'', a plant native to Sierra Leone in West Africa. Biosynthesis Unlike many other plants, ''Dichapetalum toxicarium'' can accumulate much more fluoride, even when the soil content is not particularly high. In young leaves, this is converted into monofluoroacetate, which is stored in the leaves around the flowers. During seed formation, the fluoroacetate is transferred there and converted into long-chain fluorinated fatty acids, including fluorooleic acid. Synthesis One method starts with 8-fluorooctanol, which is first reacted with phosphorus tribromide. The product of this reaction is then reacted with sodium acetylide in xylene/Dimethylformamide, DMF. Then, the reaction takes place with 1-chloro- ...

Fatty Acid
In chemistry, in particular in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated and unsaturated compounds#Organic chemistry, saturated or unsaturated. Most naturally occurring fatty acids have an Branched chain fatty acids, unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important diet (nutrition), dietary sources of fuel for animals and important structural components for cell (biology), cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oi ...
