Chemical structure of the ecdysteroid ecdysone

Ecdysteroids are insect moulting and sex hormones;[1] examples of ecdysteroids include ecdysone, ecdysterone, turkesterone and 20-hydroxyecdysone.[2] Ecdysteroids also occur in other invertebrates where they can play a different role. Phytoecdysteroids also appear in many plants mostly as a protection agents (toxins or antifeedants) against herbivore insects.[3][4]
