We have shown that adult rat liver xanthine oxidase exhibits sexual dimorphism.1 Males have greater enzyme activity by comparison to females. The increased enzyme activity in the male corresponds to a greater mass of xanthine oxidase protein.2 Immature animals of both sexes have similar enzyme activity.
