查询词典 acceptors

The success of this model gives a deep understanding of the structure of acceptors and the biological process of splicing.

该模型的成功还使得我们对剪接点上游的分支位点和嘧啶富含区的概貌有了一定的认识，加深了人们对于acceptor的结构和剪接过程的理解。

This happens in a so called reaction center inPhotosystemⅡ, where a tetrameric chlorophylls (P680) absorb the solar light andinitiate photoinduced electron transfer reaction to the acceptors, quinone A and B. Thephoto-oxidized P680 retrieves the electron from a Mn4Ca cluster via a tyrosine, thelatter components are also called oxygen evolving center. After 4 photo-processes, twomolecular water are oxidized to a molecular oxygen.

在光系统二的活性中心，叶绿素P_(680吸收太阳光，将电子传递给电子受体、醌A和醌B，同时光氧化的P_(680)~+从释氧中心中得回电子(通过Tyr_z氧化Mn4Ca簇)，经过四次光诱导电子转移，两分子水最终被氧化生成一分子氧气。

The results show that the HOMOs were mainly localized on C60, while the LUMOs were mainly localized on the substituents. This indicated that the electrons were easy to transfer from the occupied orbitals of donors to the virtual orbital of the acceptors, i.e.
