摘要
类胡萝卜素广泛合成于所有光合生物与一些非光合原核生物、真菌和少数动物;在光合生物光合器官,类胡萝卜素与叶绿素一样,是光合成与光保护必需色素;在非光合器官,充当光保护剂、抗氧化剂、颜色引诱剂和植物激素合成的前体,有利于光合生物正常的生命活动;对大多数动物与人,类胡萝卜素是经食物链传递、积累,代谢改性,呈现复杂多样的结构,在机体内具有清除自由基、抗氧化、生成维生素A、调控细胞信号通路上调抗氧化酶等特性,以预防疾病促进健康;其颜色用于动物性引诱、伪装、光保护、种间与社会关系的识别等。
Carotenoids are widely synthesized in all photosynthetic organisms and some non-photosynthetic prokaryotes,fungi and a few animals.In photosynthetic organisms,carotenoids,like chlorophyll,are essential pigments for photosynthesis and photo-protection.In non-photosynthetic organs,they act as photoprotectants,antioxidants,color attractants and the precursors of plant hormone synthesis,which is conducive to the normal life activities of photosynthetic organisms.For most animals and humans,carotenoids are transferred,accumulated and metabolized by the food chain,presenting complex and diverse structures.They have the properties of scavenging free radicals,antioxidants,generating vitamin A,regulating cell signaling pathways to upregulate antioxidant enzymes and so on,so as to prevent diseases and promote the health of the body.Carotenoids’color is used for some animal sexual attraction,camouflage,photo-protector,identification of species and social relations.
