Ecdysteroids and ovarian development in the shore crab, Carcinus maenas
Hoppe-Seyler'S Zeitschrift Fur Physiologische Chemie
|May 1, 1981
Abstract:
Mature ovaries of the shore crab Carcinus maenas contain large concentrations of three major ecdysteroids which we have identified by physicochemical methods as ecdysone, 20-hydroxyecdysone and ponasterone A. The fluctuations of ovarian and blood ecdysteroid concentrations are presented in relation to the various stages of ovarian development.
