C-peridinin is a synthetic analogue of the important, naturally-occurring carotenoid, peridinin, found in several marine algal species. C-peridinin has five conjugated carbon-carbon double bonds compared to eight possessed by peridinin and also lacks the methyl group functionalities typically present along the polyene chain of carotenoids. These structural modifications lead to unique excited state properties and important insights regarding the factors controlling the photophysics of peridinin and other carbonyl-containing carotenoids, which are critical components of the light-harvesting systems of many photosynthetic organisms.
C-多甲藻素是一种重要的天然类胡萝卜素——多甲藻素的合成类似物，多甲藻素存在于多种海洋藻类物种中。与多甲藻素拥有的八个共轭碳-碳双键相比，C-多甲藻素具有五个共轭碳-碳双键，并且还缺少通常存在于类胡萝卜素多烯链上的甲基官能团。这些结构修饰导致了独特的激发态性质，并为控制多甲藻素和其他含羰基类胡萝卜素光物理性质的因素提供了重要见解，而这些类胡萝卜素是许多光合生物光捕获系统的关键组成部分。
