Farnesol is a natural 15-carbon organic compound which is an acyclic sesquiterpene alcohol. 
Under standard conditions, Farnesol is a colorless liquid. 

Farnesol is hydrophobic, and thus insoluble in water, but miscible with oils.
Farnesol is produced from 5-carbon isoprene compounds in both plants and animals. Phosphate-activated derivatives of farnesol are the building blocks of possibly all,l acyclic sesquiterpenoids. 

These compounds are doubled to form 30-carbon squalene, which in turn is the precursors for steroids in plants, animals, and fungi. 
As such, farnesol and its derivatives are important starting compounds for both natural and artificial organic synthesis

Farnesol is found in a flower extract with a long history of use in perfumery. 
The pure substance farnesol was named (c. 1900–1905) after the Farnese acacia tree (Vachellia farnesiana), since the flowers from the tree were the commercial source of the floral essence in which the chemical was identified. 

This particular acacia species, in turn, is named after Cardinal Odoardo Farnese (1573–1626) of the notable Italian Farnese family which (from 1550 though the 17th century) maintained some of the first private European botanical gardens in the Farnese Gardens in Rome. 
The addition of the -ol ending results from Farnesol being chemically an alcohol.

The plant itself was brought to the Farnese gardens from the Caribbean and Central America, where it originates.
Farnesol is used as a deodorant in cosmetic products.

Farnesol is a signaling molecule that is derived from farnesyl diphosphate, an intermediate in the isoprenoid/cholesterol biosynthetic pathway. 
Farnesol is a 15 carbon isoprenoid alcohol is the corresponding dephosphorylated form of the isoprenoid farnesyl diphosphate. 

Farnesol has a potential role in controlling the degradation of 3-hydroxy-3-methylglutaryl coenzyme A (HMGCoA) reductase (EC, NADPH-hydroxymethylglutaryl-CoA reductase). 
The enzyme is stabilized under conditions of cellular sterol depletion (e.g. statin-treated cells) and rapidly degraded in sterol-loaded cells. 

Farnesol is dependent on the presence of both a sterol and a non-sterol derived from the isoprenoid pathway; farnesol, the dephosphorylated form of farnesyl diphosphate, can function as the non-sterol component. 
Farnesol has been shown to activate the farnesoid receptor (FXR), a nuclear receptor that forms a functional heterodimer with RXR. 

Thus, dephosphorylation of farnesyl diphosphate, an intermediate in the cholesterol synthetic pathway, might produce an active ligand for the FXR:RXR heterodimer. 
The physiological ligand for FXR remains to be identified; farnesol, may simply mimic the unidentified natural ligand(s). 

In addition, exogenous farnesol have an effect on several other physiological processes, including inhibition of phosphatidylcholine biosynthesis, induction of apoptosis, inhibition of cell cycle progression and actin cytoskeletal disorganization. 
Farnesol cellular availability is an important determinant of vascular tone in animals and humans, and provides a basis for exploring farnesyl metabolism in humans with compromised vascular function as well as for using farnesyl analogues as regulators of arterial tone in vivo. 

A possible metabolic fate for farnesol is its conversion to farnesoic acid, and then to farnesol-derived dicarboxylic acids (FDDCAs) which would then be excreted in the urine. 
Farnesol can also be oxidized to a prenyl aldehyde, presumably by an alcohol dehydrogenase (ADH), and that this activity resides in the mitochondrial and peroxisomal. 

Farnesols are able to phosphorylate farnesol to Farnesyl diphosphate in a Cytosine triphosphate dependent fashion. 
Prenol is polymerized by dehydration reactions; when there are at least four isoprene units (n in the above formula is greater than or equal to four), the polymer is called a polyprenol. 

Polyprenols can contain up to 100 isoprene units (n=100) linked end to end with the hydroxyl group (-OH) remaining at the end. 
These isoprenoid alcohols are also called terpenols. 

These isoprenoid alcohols are important in the acylation of proteins, carotenoids, and fat-soluble vitamins A, E and K. 
They are also building blocks for plant oils such as farnesol and geraniol. 

Prenol is also a building block of cholesterol (built from six isoprene units), and thus of all steroids.

Farnesol is subject to restrictions on its use in perfumery, as some people may be sensitized to it, but the evidence that farnesol can cause an allergic reaction in humans is controversial.
In one study, researchers found that in a tissue culture, Peru Balsam and farnesol were able to bind to CD1a molecules on the surface of Langerhans cells and activated T cells. 

However, researcher de Jong said, "Our work shows how these chemicals can activate T cells in tissue culture, but we must be careful to claim that this certainly works in allergic patients. 
The study paves the way for follow-up studies to confirm the mechanism in allergic patients and design inhibitors of the response." 

Despite this caveat, some popular sciences have accepted the preliminary findings of this study as conclusive evidence that farnesol induces an immunological response through this mechanism.
