Abstract: | 1. Of all the cations tested only manganese ion inhibited the benzoyl peroxide/Cu2+-dependent formation of thiobarbituric acid (TBA)-reactive substance. 2. Ki of Mn2+ for the formation of TBA-reactive substance was 5.0 microM. 3. The inhibitory manner of manganese was non competitive against copper. |
