The prothoracic glands are either of a pair of endocrine glands located in the prothorax of certain insects that regulate molting. They have an ectodermal origin and secrete ecdysteroids, such as ecdysone and 20-hydroxyecdysone. The chemical formula of ecodysin hormone is (C27H44O6).[1] They usually disappear in adults.[2]
