| 5 | 7.8 | between pH 5.0 and 7.0, myeloperoxidase converts about 90% of available hydrogen peroxide to hypochlorous acid and the remainder to hypobromous acid. Above pH 7, there is an abrupt rise in the yield of hypobromous acid. At pH 7.8, it accounts for 40% of the hydrogen peroxide | Homo sapiens |
