质体醌作为电子载体直接参预了植物内的能量传递过程,这一事实引起了人们广泛注意.醌环的取代基对醌类化合物进行光合作用的电子传递过程有很大影响,我们设想若能在保持与醌环上的甲基相近体积的条件下,将其中一个甲基换成氯原子,这样,这类化合物醌环上的电子密度显然会低于质体醌,从而进一步研究它们在光合作用中的作用,有助于进一步阐明光合作用的机制. The fact that plastoquinone as an electron carrier directly participates in the energy transfer process in plants has drawn much attention. The substituents of quinone ring have a great influence on the electron transfer process of photosynthesis of quinones. While maintaining a similar volume to the methyl group on the quinone ring, one of the methyl groups is replaced by a chlorine atom, so that the electron density on the quinone ring of such compounds is clearly lower than that of the plastoquinone, Role in the role of help to further clarify the mechanism of photosynthesis.
