Synthesis of ecdysone-14C and ecdysterone-14C from cholesterol-14C in cockroaches (Periplaneta americana) without molting glands.

M Gersch, H Eibisch.   

Abstract

The synthesis of molting hormone of cockroaches of which the prothoracic glands had previously been extirpated was investigated after injection of cholesterol-14C. It could be proved by means of radio thin-layer chromatography of extracts that ecdysterone and in small amounts ecdysone are synthesized in Periplaneta americana larvae without prothoracic glands. The results demonstrate that other tissues are also able to perform the molting hormone besides the molting gland itself.
