The best results are achieved when hydroquinone is employed as a free radical quencher. The addition of free radical quenchers in the system also decreased the molecular weights of polymers. The higher polymer yields and lower molecular weights are due to the predominant participation of ionic ...

an example of which may be the leakage of electrons from the mitochondrial electron transport chain to generate superoxide radical (O2−). Others are generated for useful purposes, such as the role of nitric oxide in neurotransmission and ...
71) Based on different action principle, light stabilizers were defined as ultraviolet light screening agent, ultraviolet absorbent, quencher and free radical catching agent. 72) The results showed that C. trompe can cause accumulation of oxygen free radical, reduce anti-oxidizing ability, and lead ...
It is concluded that SQ functions as an efficient quencher of singlet oxygen and prevents the corresponding part of lipid peroxidation in human skin surface. 展开 关键词: free radicals, lipid peroxidation DOI: 10.1016/0005-2760(95)00005-W ...

DABCYL DBCO quencher can effectively control free radical reactions and avoid unexpected situations caused by chain reactions. This precise control not only helps scientists better understand the essence of chemical reactions, but also provides strong support for the synthesis of new materials, drug devel...
Define Polymer chain. Polymer chain synonyms, Polymer chain pronunciation, Polymer chain translation, English dictionary definition of Polymer chain. n. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to
(β-Car) is known to be a quencher of singlet oxygen, whereas α-tocopherol (α-Toc) is a quencher of free radicals. Accordingly, the identification of the oxidation mechanism that induces the oxidation of SQ (e.g. singlet oxygen oxidation and free radical oxidation) is necessary in order...
