质体醌

在叶绿体中，光系统Ⅱ（PSⅡ）是类囊体膜上的一个大的色素蛋白质复合物，利用光能催化水的氧化以及质体醌的还原。

Photosystem II ( PSII ), which catalyzes light-dependent water oxidation and plastoquinone reduction in chloroplasts , is a large pigment-protein complex in the thylakoid membrane .

光系统Ⅱ（PSⅡ）是绿色植物光合膜上存在的两个光反应中心之一，具有利用太阳光的能量来裂解水、释放分子氧并还原质体醌的功能。

PSII functions as a water / plastoquinone oxidoreductase in the thylakoid membrane of chloroplasts and cyanobacteria , comprising one of the light reaction centers for photosynthesis .

在植物体内，尿黑酸是维生素E和质体醌的前体，所以HPPD又间接控制着这两类物质的合成。

In plants , homogentisate is the precursor of vitamin E and plastoquinones , therefore HPPD also plays a key role in the biosynthesis of this two kinds of substances .
