高等植物叶黄素合成代谢与调控机制

Biosynthesis Metabolism and Regulation Mechanism of Lutein in Higher Plants

摘要: 叶黄素(lutein)是C₄₀的萜类化合物,结构中含紫罗酮环,广泛存在于自然界中。叶黄素是高等植物光系统中主要的光合色素,能捕获光能供叶绿素进行光合代谢。叶黄素在预防视网膜黄斑变性、白内障、癌症及心血管疾病等方面有重要作用。本文综述高等植物叶黄素的生物代谢途径与其关键酶的作用和调控机制,并对今后的重点探索方向和优先研究内容提出建议。

Abstract: Lutein is a kind of C₄₀ terpenoid compound with the ionone ring systems distributed widely in nature. It is the predominant carotenoid pigment in higher plants to capture the sunlight for photosynthesis of chlorophyll. In addition,lutein plays an important role in the prevention of retinal macular degeneration,cataract,cancer and cardiovascular disease. This paper summarized metabolism pathway,the function and regulation mechanism of key enzymes involoved in lutein synthesis in higher plants. Furthermore,it put forward strategic suggestions on the future exploration directions and research priorities.
