Definition of terpenoid in English:

terpenoid

noun ˈtəːpɪnɔɪdˈtərpəˌnoid

Chemistry

Any of a large class of organic compounds including terpenes, diterpenes, and sesquiterpenes. They have unsaturated molecules composed of linked isoprene units, generally having the formula (C₅H₈)n.
Example sentencesExamples
- The nectar is sucrose-dominant but also contains low concentrations of glucose, fructose, free amino acids and possibly terpenoids.
- Many species endemic in Australia are known to synthesize and accumulate significant quantities of volatile terpenoids.
- However, the vast majority of terpenoids are classified as secondary metabolites, compounds not required for plant growth and development but presumed to have an ecological function in communication or defense.
- Agents used in household cleaning compositions are composed of structurally diverse classes of chemicals, including surface active agents, phenols, and terpenoids.
- Because these terpenoids contain many functional groups - mainly unsaturated and saturated aldehydes and ketones - how they exert their antimicrobial activity is not well understood.
