Triterpene - Wikipedia
Triterpenes are a class of terpenes composed of six isoprene units with the molecular formula C 30 H 48; they may also be thought of as consisting of three terpene units. Animals, plants and fungi all produce triterpenes, including squalene, the precursor to all steroids. [1][2] Triterpenes exist in a great variety of structures.
