WebFeb 27, 2011 · Copper is incorporated into a number of metalloenzymes involved in hemoglobin formation, drug/xenobiotic metabolism, carbohydrate metabolism, catecholamine biosynthesis and the cross-linking of collagen, elastin, and hair keratin as well as in the antioxidant defense mechanism [ 1 ]. WebAppendix A-4 The element copper forms two principal series of compounds based on +1 and +2 ionic charges. When one electron in the outermost energy level of copper ([Ar]3d104s1) is removed, the +1 oxidation state is exhibited; when an additional electron from the underlying energy level is removed the +2 oxidation state results.
