These are terpenes that contain 15 carbon atoms and are comprised of three isoprene units. The biosynthesis of sesquiterpenes is known to occur mainly through the mevalonic acid pathway (MVA; PMID:17467679), in the cytosol. However, recent studies have found evidence of pathway crosstalk with the methyl-eritritol-phosphate (MEP; PMID:23746261) pathway in the cytoplasm. Farnesyl diphosphate (FPP) is a key intermediate in the biosynthesis of cyclic sesquiterpenes. FPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Humulene is is a pale yellowish green clear liquid, soluble in alcohol that is barely soluble in water. It has a woody odor and adds a woody, oceanic-watery, spicy-clove note to perfumes ( http://www.thegoodscentscompany.com/data/rw1027221.html#tooccur). It contributes to the taste of the spice Persicaria odorata or Vietnamese coriander. Humulene is found in hops (Humulus lupulus; doi:10.1055/s-2006-962205), from which its name was derived. It is often found together with its isomer beta-caryophyllene in many other aromatic plants such pine trees ( PMID: 17396639), orange trees, marsh elders, tobacco, sunflowers, Salvia officinalis (common sage, culinary sage), Lindera strychnifolia Uyaku (Japanese spicebush, ginseng species and the Zingiberaceae (the ginger family). alpha-humulene, a very reactive volatile organic compound emitted by many organic plants, quickly combines with ozone in sunlight (photooxidation) to create secondary organic aerosols ( oi:10.1039/c0cp02379e). alpha-humulene has antibacterial and anti-biofilm properties against Bacteroides fragilis (PMID: 32073898) and demonstrated anti-inflammatory properties in an ovalbumin-induced model of airway allergic inflammation (PMID: 19438512).
