Synthesis of apolar esters by ovaries of the cockroach Periplaneta americana

General and Comparative Endocrinology 70(1): 74-82

Synthesis of apolar esters by ovaries of the cockroach Periplaneta americana

Ecdysteroid levels detected by RIA in extracts of mature ovaries from P. americana increased about 4-fold (from 53 to 184 ng/g) on treatment with Helix pomatia 'sulphatase' enzymes. HPLC analysis showed that this increase in immunoreactivity resulted from the hydrolysis of 6 apolar compounds that cochromatographed with the ecdysteroid esters present in newly laid oothecae (A1, A2, A3, A4, A5 and A6).
