The isolated and purified chloroplast envelope of spinach leaves contains, besides carotenoids, several prenylquinones as basic constituents: plastoquinone-9, phylloquinone K1, alpha-tocoquinone and the chromanol, alpha-tocopherol. The relative quinone and carotenoid composition of the envelope differs distinctively from that of the thylakoid membranes. The possible role of prenylquinones in metabolic envelope activities and the mediator function of the envelope in prenylquinone biosynthesis are discussed.
除类胡萝卜素外，菠菜叶中分离纯化得到的叶绿体被膜还含有几种作为基本成分的异戊二烯醌：质体醌-9、叶绿醌K1、α-生育醌和色满醇α-生育酚。被膜的醌和类胡萝卜素相对组成与类囊体膜明显不同。文中讨论了异戊二烯醌在被膜代谢活动中的可能作用以及被膜在异戊二烯醌生物合成中的介导功能。
