Monoterpenes are a class of terpene s that consist of two isoprene units and have the molecular formula C sub 10 sub H sub 16 sub . Monoterpenes may be linear acyclic or contain rings. Biochemical modifications such as redox oxidation or rearrangement reaction rearrangement produce the related monoterpenoids . Acyclic Biosynthetically, isopentenyl pyrophosphate and dimethylallyl pyrophosphate are combined to form geranyl pyrophosphate . Image Geranyl pyrophosphate.png thumb 300px none Geranyl pyrophosphate Image Myrcen.png thumb right 80px Myrcene, a monoterpene Elimination of the pyrophosphate group leads to the formation of acyclic monoterpenes such as ocimene and the myrcene s. Hydrolysis of the phosphate groups leads to the prototypical acyclic monoterpenoid geraniol . Additional rearrangements and oxidations provide compounds such as citral , citronellal , citronellol , linalool , and many others. Many monoterpenes found in marine organisms are halogen ated, such as halomon . Monocyclic In addition to linear attachments, the isoprene units can make connections to form rings. The most common ring size in monoterpenes is a six membered ring. A classic example is the cyclization of geranyl pyrophosphate to form limonene . Image LimoneneBiosynthesis.png 600px The terpinene s, phellandrene s, and terpinolene are formed similarly. Hydroxylation of any of these compounds followed by dehydration can lead to the aromatic p cymene . Important terpenoids derived from monocyclic terpenes are menthol , thymol , carvacrol and many others. Bicyclic Geranyl pyrophosphate can also undergo two sequential cyclization reactions to form bicyclic monoterpenes, such as pinene which is the primary constituent of pine pine resin . Image PineneBiosynthesis.png 600px Other bicyclic monoterpenes include carene , sabinene , camphene , and thujene .
