All substances produced in plant cells are not necessarily the result of enzyme-catalyzed
reactions. The alkaloid nitraramine, which contains seven stereogenic centers, is present in
Nitraria schokeri as a racemate. Isolation of a chiral metabolite might be due to spontaneous
nonenzymatic reactions starting from an achiral precursor followed by enzyme-catalyzed
metabolism of one of the enantiomers (Wanner and Koomen, 1995).

各种物质在植物细胞产生的结果不一定是酶的催化 反应. nitraramine的盐碱地,其中七stereogenic中心,位于 NitrariaSchokeri作为外消旋物. 孤立的代谢物,可能是因为手性自发 前身是由achiralnonenzymatic反应后酶的催化 对映异构体的代谢(WannerKoomen和1995年).
