20-Hydroxyecdysone
In arthropods, 20-hydroxyecdysone acts through the ecdysone receptor. Ecdysone and 20-hydroxyecdysone regulate larval molts, onset of puparium formation, and metamorphosis.

Molting hormone (ecdysteroid) is one of the most important hormones in insects. The synthesis and inactivation of the ecdysteroid regulate the developmental process of insects. A major pathway of ecdysone inactivation is that ecdysone is converted to 3-dehydroecdysone, and then further to 3-epiecdys …
