Abstract

Oxygenic photosynthesis is one of the main sources of reactive oxygen species (ROS). In the cells of photosynthetic organisms, the mechanism of maintaining a balance between oxidative and antioxidant processes includes both enzymatic and nonenzymatic defense systems that are already formed in prokaryotic cells. The review presents current data on the main mechanisms of ROS formation in cyanobacteria and plant cells, a comparative analysis of the main groups of low molecular weight antioxidants (ascorbic acid, glutathione, tocopherols, carotenoids, anthocyanins, polyamines, etc.) and their contribution to ROS detoxification and cellular protection from oxidative stress.

蓝细菌和植物细胞中的低分子量抗氧化剂

摘要

生氧的光合作用是活性氧（ROS）的主要来源之一。在光合生物的细胞中，维持氧化和抗氧化过程之间平衡的机制包括原核细胞中已经形成的酶和非酶防御系统。综述提供了有关蓝细菌和植物细胞中ROS形成的主要机理的最新数据，对低分子量抗氧化剂的主要组（抗坏血酸，谷胱甘肽，生育酚，类胡萝卜素，花青素，多胺等）的比较分析。 ROS排毒和细胞保护免受氧化应激。
