Terpene - Wikipedia
网页Conceptually derived from isoprenes, the structures and formulas of terpenes follow the biogenetic isoprene rule or the C5 rule, as described in 1953 by Leopold Ružička [26] and colleagues. [27] The C 5 isoprene units are provided in the form of dimethylallyl pyrophosphate (DMAPP) and isopentenyl pyrophosphate (IPP).

Chemistry Matters—Terpenes: Naturally Occurring Alkenes
网页Chemically, plant essential oils consist largely of mixtures of compounds called terpenoids—small organic molecules with an immense diversity of structure. More than 60,000 different terpenoids are known. Some are open-chain molecules, and others contain rings; some are hydrocarbons, and others contain oxygen.

网页2022年11月11日 · The structure of terpenes is based on the linkage of isoprene units (C 5 H 8) such as dimethylallyl pyrophosphate and isopentenyl pyrophosphate [8,9]. These two C5 building blocks generate various terpene compounds by head-to-tail condensation .
Terpene - an overview | ScienceDirect Topics
网页Terpenes are an important group of aromatic compounds characterizing the odor of many flowers, fruits, seeds, leaves, woods, and roots. As such, terpenes are often important in the fragrance of herb-flavored wines such as vermouth and fruit-flavored wines. In addition, they also characterize the aromas of several grape varieties.
