活性氧类 Reactive oxygen species(重定向自Reactive oxygen)
![]() 活性氧类(英语:Reactive oxygen species,ROS),是生物有氧代谢过程中的一种副产品,包括氧离子、过氧化物和含氧自由基等。这些粒子相当微小,由于存在未配对的自由电子,而十分活跃。过高的活性氧水平会对细胞和基因结构造成损坏。活性氧,为含氧的,具有化学活性的分子。包括氧离子(oxygen ion)及过氧化氢(peroxide).因为核外的未配对电子的存在,具有很强的化学反应活性。ROS是正常氧代谢的副产物,并且在细胞信号传导,和保持机体恒常性起很大作用。然而,在时间以及外界环境影响下(例,暴露于紫外线(UV exposure)或热源(heat exposure)下等),ROS的量会急剧增多。引起这种改变的原因有可能是由于明显的细胞结构的损坏。这种显现,被称为氧化应激。ROS也可能由外界的因素生成,如致电离辐射。

Reactive oxygen species 活性氧类(重定向自Reactive oxygen)
![]() ![]() ![]() Reactive oxygen species (ROS) are chemically reactive molecules containing oxygen. Examples include peroxides, superoxide, hydroxyl radical, and singlet oxygen. In a biological context, ROS are formed as a natural byproduct of the normal metabolism of oxygen and have important roles in cell signaling and homeostasis. However, during times of environmental stress (e.g., UV or heat exposure), ROS levels can increase dramatically. This may result in significant damage to cell structures. Cumulatively, this is known as oxidative stress. ROS are also generated by exogenous sources such as ionizing radiation. |
