查询词典 emerald copper

The favorable regions for DNA cleavage were observed to be pH 3.6-5.6 and pH 9.0-10, suggesting that the species responsible for DNA cleavage are different in different pH regionsOur results do not support a widely accepted conclusion that the copper-bound or free hydroxyl radicals provided by CuZnSOD with its end product hydrogen peroxide lead to release of copper from its host, the Fenton reaction between the free copper and the hydrogen peroxide being responsible for the aberrant copper-mediated oxidation chemistry in CuZnSOD.

High dose copper can also decrease SA, PE content and increase SM, PS content.These showed that high dose can induce injury of erythrocyte by changing elementary structure and moity of membrane protein and membrane phospholipid, which may be one of the mechanisms of goat erythrocyte damage induced by high dose copper. 2. High copper caused the decrease of SOD and GSH-PX activity and the increase of MDA content.
