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.
萜类化合物；类萜
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.
