45,46 This state overlaps strongly with the corresponding σ-bonding interaction, found at slightly higher energy than the π bond (21,900 cm−1 in nitrite reductase), giving this enzyme a green colour.46 Other proteins exist that have intermediate structures and spectra, e.g., cucumber ...
Copper sulfate is the electrolyte when electrolytic refined copper. After several purification and filtration electroplating grade copper sulfate can reach high purity. It will gradually lose crystal water when it is place in the air for a long time and change into white. Industrial Grade: Used...
