叶绿素及其相关色素在光合作用的光收集和初级电荷分离反应中起着核心作用。叶绿素有几种类型，其中叶绿素a一直被认为是在含氧光合作用中吸收波长最长光的常见种类。然而，近年来，另外两种类型的叶绿素叶绿素d和叶绿素f被发现对几种蓝藻很重要，它们的吸收最大值都比叶绿素a长。叶绿素的多样性是供氧光合生物适应各种光环境的重要因素。本章简要概述了叶绿素种类的多样性，并讨论了它们在光合能量转化反应中的功能作用，重点介绍了近年来叶绿素d和叶绿素f的结构和功能的研究结果。
Chlorophylls and related pigments play central roles in light-harvesting and primary charge separation reactions of photosynthesis. There are several types of chlorophylls, among which, chlorophyll a has long been believed to be the common species that absorbs the longest wavelength light in oxygenic photosynthesis. In recent years, however, two other types of chlorophylls, chlorophyll d and chlorophyll f, both with absorption maxima longer than that of chlorophyll a, were found to be important for several species of cyanobacteria. The diversity of chlorophylls is an important factor for the oxygenic photosynthetic organisms to adapt to various light environments. This chapter briefly summarizes the diversity of chlorophyll species and discusses their functional roles in the photosynthetic energy conversion reactions, with emphases on the results of studies on the structures and functions of chlorophyll d and chlorophyll f that were achieved in recent years.
