Carotenoids play a number of important roles in photosynthesis, primarily providing light-harvesting and photoprotective energy dissipation functions within pigment–protein complexes. The carbon–carbon double bond (C=C) conjugation length of carotenoids (N), generally between 9 and 15, determines the carotenoid-to-(bacterio)chlorophyll [(B)Chl] energy transfer efficiency. Here we purified and spectroscopically characterized light-harvesting complex...

光合天线复合体放弃了类胡萝卜素到细菌叶绿素的能量转移效率,以确保光保护作用[生物化学]

类胡萝卜素在光合作用中起着许多重要作用,主要在色素-蛋白质复合物内提供捕光和光保护能量消散的功能。类胡萝卜素(N)的碳-碳双键(C = C)共轭长度通常在9至15之间,这决定了类胡萝卜素到(细菌)叶绿素[(B)Chl]的能量转移效率。在这里,我们纯化并在光谱上表征了采光复合物...
