TerpenesUnitsIsopreneExamples

Terpenes2

• The single isoprene unit, therefore, represents the most basic class of terpenes, the hemiterpenes. (researchsquare.com)
• Terpenes of five units of HEMITERPENES , formed from geranylfarnesyl pyrophosphate. (nih.gov)

Units2

• C20) and triterpenes (C30) contain two and three terpene units respectively. (researchsquare.com)
• A class of compounds composed of repeating 5-carbon units of HEMITERPENES. (wakehealth.edu)

Isoprene2

• Isoprene-formally a hemiterpene-and selected examples of monoterpenes (which consist of two isoprene units), sesquiterpenes (1.5 terpene, i.e., 3 isoprene units as in farnesene, contained in agro-industrial wastes, and β-carophyllene), a diterpinol (retinol, also known as vitamin A1), a triterpene (squalene, precursor to steroid hormones) and a tetraterpene (α-carotene) are shown. (aramram.tv)
• Hemiterpenes: composed of a single isoprene unit with five carbons. (thetreecbd.com)

Examples1

• Examples of terpenoids built from hemiterpene oligomerization are: Azadirachtin, present in Azadirachta indica, the (Neem tree) Artemisinin, present in Artemisia annua, Chinese wormwood Tetrahydrocannabinol, present in Cannabis sativa, cannabis Saponins, glycosylated triterpenes present in e.g. (wikipedia.org)
