The cell membrane through lipid peroxidation

According to the standard, the oxygen content is not greater than 0. 1 and No.　　 OFC (oxygen-free copper): metallic copper with a purity of 99.97%, the oxygen content is not more than 0.996%, which is divided into PC -OCC and UP-OCC etc.003%, the total impurity content is not greater than 0.05%.995% and OCC (single-crystal oxygen-free copper): highest purity,

above 99. 2 oxygen-free copper.003%, and the total impurity content is not more than 0.Pure copper that does not contain oxygen or any deoxidizer residues.95%, the oxygen content is not more than 0. Among them, there are LC-OFC (linear crystalline oxygen-free copper or crystalline oxygen-free copper) in oxygen-free copper: purity above 99. 2 oxygen-free copper reaches 99.　　 Oxygen-free copper has no hydrogen embrittlement, high conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance.05%, and the purity of copper is greater than 99. Different countries have different standards for oxygen content, and there are certain differences.　　

Using UP-OCC technology (Ultra Pure Copper by Ohno Continuous Casting Process) made of single crystal oxygen-free copper, non-directional, high purity, anti-corrosion, and extremely low electrical impedance makes the wire suitable for high-speed and high-quality signal transmission. But in fact it still contains a very small amount of oxygen and some impurities.003%, and the total impurity content is not more than 0.03%; the purity of No.995%..

The purity of No. 1 oxygen-free copper reaches 99.　　 According to the oxygen content and impurity content, oxygen-free copper is divided into  No.95%. It is generally used in electrical and electronic applications such as audio equipment, vacuum electronic devices, and cables.Among them, the hydroxyl radicals are the most toxic, which not only damages the cell membrane through lipid peroxidation, but also destroys the genetic material of the nucleus, resulting in cell death. The mystery is that the iron in hemoglobin is ferric iron ions, but the source of food is the separation of ferric iron.
