Synonyms: terpenes, a terpene

Superclasses: a lipidan isoprenoid
a secondary metabolite

Terpenoids make up a very large family of natural products containing more than 50,000 structurally diverse compounds. They are categorized by the number of C5 isoprene units as follows:

Hemiterpenoids (one C5 unit), monoterpenoids (C10; two C5 units), sesquiterpenoids (C15; three C5 units), diterpenoids (C20; four C5 units), sesterterpenoids (C25; five C5 units), triterpenoids (C30; six C5 units), sesquarterpenoids (C35; seven C5 units), and tetraterpenoids (C40; eight C5 units).

Child Classes: a diterpenoid (234), a hemiterpene (1), a homoterpenoid (2), a meroterpenoid (7), a monoterpenoid (53), a sesquarterpenoid (2), a sesquiterpenoid (270), a sesterterpene (17), a terpenoid derivative (94), a tetraterpenoid (160), a triterpenoid (185)
