Abstract Incubation of cycloeucalenol with microsomes of Zea mays embryos in 2 H 2 O yields obtusifoliol-[19- 2 H]. Only one 2 H atom is incorporated into obtusifoliol during the enzymatic reaction. This has been demonstrated using NMR spectroscopy by correlation of the enzymatically obtained product with 2 HCl isomerization products of cycloeucalenol.
摘要 环桉油精与玉米胚的微粒体在 2 H 2 O 中孵育产生钝叶酚-[19- 2 H]。在酶促反应过程中,只有一个 2 H 原子结合到钝叶醇中。这已通过使用 NMR 光谱法通过酶促获得的产物与环桉油精的 2 种 HCl 异构化产物的相关性得到证实。
