查询词典 radical

Free radical hurts biological large molecules, lets lipid peroxid- ize and damages membrane, the weakening of antiperoxidation system in vivo (vit E, SOD, GSH-PX) will increase the harmful effect of radical on cells.

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.

A novel method combining a conventional free-radical solution polymerization with a chemical saponification was used to synthesize a, cu-dicarboxyl terminated oligo s with molecular weight below 1500. Here, cn-carboxyl terminated oligo s were firstly synthesized by the free-radical polymerization in THF, where 4,4'-azobis(4-cyanovaleric acid) was used as initiator, thioglycolic acid as chain transfer agent, then CTBMA were transformed into di-CTBMA via saponifying CTBMA in dioxane/H_2O/KOH solution.
