活性氧（ROS）是生物体中至关重要的信号分子，能够调控多种生物过程。在植物体内，基础ROS水平不仅介导正常的生长发育，还通过精细调控的氧化还原网络通路，调控代谢、衰老及程序性细胞死亡等关键生理功能。此外，当植物遭受生物或非生物胁迫（如病原体侵袭、干旱或创伤）时，ROS会迅速积累，从而对作物产量产生不利影响。其中，过氧化氢（H2O2）被认为是主要的ROS，在细胞间和细胞内通讯中发挥关键信号转导作用。

When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of ...

Scientists have developed two new covalent organic frameworks (COFs) that efficiently produce hydrogen peroxide — a valuable ...

BOSTON, Mass. (June 3, 2009)—When you were a kid your mom poured it on your scraped finger to stave off infection. When you got older you might have even used it to bleach your hair. Now there's ...

Hydrogen peroxide (H2O2) is an important chemical, with a wide variety of applications. However, the current method used to manufacture H2O2 is expensive and generates a considerable amount of waste, ...

Scientists at UC Davis Health have discovered that an enzyme in the colon lining releases hydrogen peroxide (H 2 O 2) - a known disinfecting compound- to protect the body from gut microbes. Their ...

Micron-sized water droplets condensed from water vapor contain small amounts of hydrogen peroxide, according to a study. When water is atomized into micron-sized droplets, water molecules can become ...
