Triterpene
Triterpenes are a class of chemical compounds composed of three terpene units with the molecular formula C30H48; they may also be thought of as consisting of six isoprene units. Animals, plants and fungi all produce triterpenes, including squalene, the precursor to all steroids. Structures Triterpenes exist in a great variety of structures. Nearly 200 different skeletons have been identified. These skeletons may be broadly divided according to the number of rings present. In general pentacyclic structures (5 rings) tend to dominate. Squalene is biosynthesized through the head-to-head condensation of two farnesyl pyrophosphate units. This coupling converts a pair of C15 components into a C30 product. Squalene serves as precursor for the formation of many triterpenoids, including bacterial hopanoids and eukaryotic sterols. Triterpenoids By definition triterpenoids are triterpenes that possess heteroatoms, usually oxygen. The terms ''triterpene'' and ''triterpenoid'' oft ...

Ganoderma Lucidum
''Ganoderma lucidum'' is a red-colored species of ''Ganoderma'' with a limited distribution in Europe and parts of China, where it grows on decaying hardwood trees. Wild populations have been found in the United States in California and Utah, but were likely introduced anthropogenically and naturalized. Etymology The scientific name, ''Ganoderma lucidum'', uses the genus name, ''Ganoderma'' (derived from the Greek ganos/γάνος "brightness, sheen", hence "shining" and derma/δέρμα "skin") combined with ''lucidum'' from Latin for "lucidus" as light, bright or clear. Taxonomy and history The history of the ''Ganoderma lucidum'' taxon is tied to the history of ''Ganoderma'' as a genus. Karsten first described the ''Ganoderma'' in 1881 and included only one species in the genus, ''G. lucidum'' (Curtis) Karst. Previously, it was called ''Boletus lucidus'' Curtis (1781) and then ''Polyporus lucidus'' (Curtis) Fr. (1821). Patouillard revised Karsten's genus Ganoderma to include ...
