Definition of diterpene in English:

diterpene

noun dʌɪˈtəːpiːn

Chemistry

Any of a group of terpenes found in plant gums and resins, having unsaturated molecules based on a unit with the formula C₂₀H₃₂.
〔化〕二萜（烯）
Example sentencesExamples
- In conifers, for example, the diterpene content of resin has a direct influence on the rate of resin crystallization.
- Structurally diverse compounds including diterpenes, prostaglandins and steroids have been described in octocorals.
- Correlations among all sesquiterpenes and among all diterpenes were also significant and positive for yellow-cedars (except for one minor diterpene).
- Excessive amounts of these materials, which contain diterpene alkaloids particularly aconitine, can produce toxic effects and occasional fatalities.
- The active biochemical constituents are called guggulsterones, which contain diterpenes, sterols, esters and fatty alcohols.

Derivatives

diterpenoid

noun & adjective

Chemistry

Abscisic acid (a sesquiterpenoid) and the gibberellins (diterpenoids) are growth regulators.
Example sentencesExamples
- They contain the highly toxic C19 diterpenoid alkaloids of aconitine, mesaconitine and hypaconitine.
- Many conifers produce oleoresin, a complex mixture of mono-, sesqui- and diterpenoids.
- These investigators revealed diterpenoids as the off-flavor culprit that can be problematic in forage-finished beef.
- Some specialist sawfly adults sequester diterpenoids for protection against predatory birds and lizards.
