Abstract
- Ecdysteroids were detected in extracts of egg-producing adult Caenorhabditis elegans, in dauer larvae and in dietary bacteria. 2. Similar concentrations of free ecdysteroids were recorded in adults and larvae, although the two life cycle stages differed in their ratio of ecdysone: 20-hydroxyecdysone. 3. Patent adults metabolized [3H]ecdysone into apolar products and putative [3H]ecdysone 22-phosphate.
摘要
- 在产卵的成年秀丽隐杆线虫提取物、 dauer 幼虫和食物细菌中检测到蜕皮甾类。2. 尽管成虫和幼虫这两个生命周期阶段的蜕皮激素与 20-羟基蜕皮激素的比例不同，但记录到的游离蜕皮甾类浓度相似。3. 成熟成虫将[3H]蜕皮激素代谢为极性产物和假定的[3H]蜕皮激素 22-磷酸酯。
