Hydroxyl Radical 98-106 LOC100508689 Homo sapiens 88-93 3605340-4 1987 We found that both native and pronase-treated mucin effectively scavenged hydroxyl radical and that the scavenging properties were not significantly different. Hydroxyl Radical 74-90 LOC100508689 Homo sapiens 46-51 3605340-8 1987 These data suggest that hydroxyl radicals derived from the iron-catalyzed decomposition of hydrogen peroxide are responsible for the depolymerization of native mucin. Hydroxyl Radical 24-41 LOC100508689 Homo sapiens 160-165
