释义

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.
