类胡萝卜素在光合作用中的基本功能是充当光保护剂，防止叶绿素和细菌叶绿素在氧气存在下引起有害的光破坏反应。根据最近对紫色光合细菌反应中心和天线复合物的结构研究，描述了类胡萝卜素的详细组织。然后，具体参考细菌天线复合物，介绍了光保护作用、三重态-三重态能量转移的细节。
The essential function of carotenoids in photosynthesis is to act as photoprotective agents, preventing chlorophylls and bacteriochlorophylls from sensitizing harmful photodestructive reactions in the presence of oxygen. Based upon recent structural studies on reaction centres and antenna complexes from purple photosynthetic bacteria, the detailed organization of the carotenoids is described. Then with specific reference to bacterial antenna complexes the details of the photoprotective role, triplet-triplet energy transfer, are presented.
