合成物质

Among them, the transition metals promoted dearomatization proceed under mild reaction conditions with various substrates, and which could be applied for synthesis of bioactive compounds.

其中，过渡金属参与的脱芳构化，条件温和、物广泛，可用于生物活性物质的合成。

Then their synthese speed slows down.But the synthese of RNA and DNA inthe follicular cell is continuous during vitellogenesis, which may relate toformation of livetin.

而滤细胞卵母细胞卵黄形成期，它的RNA和DNA的合成均较快，因此认为滤细胞合成分泌了一些物质参与卵黄蛋白的形成。
