“Although apparently in contrast with the common view that Cu(I) and not Cu(II) is the … of LDL oxidation in the copper model, the results reported here indicate that the availability of Cu(I) during the initiation phase of … by copper antagonizes both antioxidant consumption and … extensive oxidation.”
“Furthermore, the direct addition of Cu(I) , together with Cu(II), to a suspension of isolated LDL efficiently delayed the onset of extensive lipid peroxidation and decreased the rate of antioxidant consumption.”
“Moreover, the initial rate of Cu(II)-induced consumption of either endogenous antioxidants in LDL or free alpha-tocopherol in suspension was increased in the presence of BC, thus indicating that the continuous removal of Cu(I) enhanced both antioxidant consumption and LDL oxidation promoted by copper.”
