翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Triterpene ： ウィキペディア英語版 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 create triterpenes, with arguable the most important example being squalene as it forms the basis of almost all steroids. ==Diterpene structures== Triterpenes exist in a huge variety of structures with nearly 200 different skeletons known from natural sources or enzymatic reactions. These may be broadly divided according to the number of rings present; although in general pentacyclic structures (5 rings) tend to dominate. ==Triterpenoids== By definition triterpenes are hydrocarbons and possess no heteroatoms, functionalized triterpenes should instead be called triterpenoids; however this distinction is not always adhered to in scientific literature, with the two terms often being used interchangeably. Triterpenoids possess a rich chemistry and pharmacology (e.g. Cholesterol) with several pentacyclic motiefs; particularly lupane, oleanane and ursane showing promise as anti-cancer agents. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Triterpene」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
