Ecdysone is a steroidal prohormone of the major insect molting hormone 20-hydroxyecdysone , which is secreted from the prothoracic glands . Insect molting hormones (ecdysone and its homologues) are generally called ecdysteroids . Ecdysteroids act as moulting hormones of arthropods but also occur in other related phyla where they can play different roles. In Drosophila melanogaster , an increase in ecdysone concentration induces the expression of genes coding for proteins that the larva requires, and it causes chromosome puffs (sites of high expression) to form in polytene chromosomes. Recent findings in Chris Q. Doe lab have found a novel role of this hormone in regulating temporal gene transitions within neural stem cells.  Ecdysone and other ecdysteroids also appear in many plants mostly as a protection agent (toxins or antifeedants) against herbivorous insects. These phytoecdysteroids have been reputed to have medicinal value and are part of herbal adaptogenic remedies like Cordyceps , yet an ecdysteroid precursor in plants has been shown to have cytotoxic properties.  A pesticide sold with the name MIMIC has ecdysteroid activity, although its chemical structure has little resemblance to the ecdysteroids.
Hi Penny! Hmmm, that’s strange that you weren’t able to comment on the shrimp recipe (you should be able to scroll down past the recipe (there are a few ads), then you should see “Leave a comment.” Unfortunately though, we’re not really sure there’s a way to do this with pre-cooked shrimp. Cooking them in the oven with the prosciutto will likely overcook them and dry them out. You could thaw the shrimp and try cooking the prosecute in a pan, but it will probably get too crisp to wrap around the shrimp without crumbling or breaking. :/ We’re sorry we’re not much help, but we hope you can still try the recipe!
