查询词典 singlet

We have proven that the accumulation of superoxide will be dangerous by disproportioning to other deleterious ROS such as H〓O〓 and ·OH, although superoxide is less harmful than singlet oxygen because of the capability of artificial quinone to partially prevent PS Ⅱ reaction center complexes from photodamage.

发现受到光抑制破坏的PS Ⅱ仍能生成O〓，尽管重组醌对PS Ⅱ反应中心复合物的保护作用表明O〓对PS Ⅱ的破坏性可能不如单线态氧强，但它可以通过诱发生成的其它活性氧物种，如H〓O〓和·OH等，导致对PS Ⅱ造成显著的破坏，因而过多的O〓生成对高等植物是有害的。

Rresults from those studies can be summariazed as follow:(1) A preliminary study no correlationship between the UV-VIS reflection spectrum of tomato fruit surface and the lycopene amount of tomato fruit was undertaken. Based on observation from this study, a damage-free and in-situ detection technique of lycopene amount from tomato was developed with UV-VIS reflection spectroscopy;(2) The geometrical isomers of lycopene were separated successfully on C30-HPLC-PDA-ELSD. The absorption coefficients of Z-isomers were consequently dedermined. The geometrical isomer composition of lycopene could therefore be assessed. Those efforts formed a solid base to identify the natural product from synthetic compound of lycopene;(3) Lycopene resource from the fruit of Autumn oliver was proved to be available for industrial application. An extraction methos of lycopene from the fruit of Autumn oliver by supercritical carbon dioxide was developed at laboratory scale;(4) A method to extract lycopene by supercritical liquid with improved efficiency was developed; Data from this investigation suggested that a proper raw material pre-extraction process was important for a better extraction efficiency;(5) Variation in the geometrical isomer composition of lycopene during its metabolish in rat was assessed. A large amount of Z-isomers were observed. This variation took place in serum;(6) The absorption rate and accumulation in serum of natural lycopene in rat were assessed;(7) Ability to quench singlet oxygen by different geometrical isomers of lycopene was compared;(8) It was detected that whether natural lycopene had functions to regule blood-lipids and LDL antioxidation;(9) A C31 degradation piece of lycopene was found in the prostate gland of rat.
