title: Denitrosation of N-nitrosodimethylamine and N-nitrosomethylurea by liver microsomes from trout (Salmo gairdneri Rich.).
abstract: N-Nitrosodimethylamine and N-nitrosomethylurea are partially metabolized to nitrite and formaldehyde by trout liver microsomes. Results show that the denitrosation pathway of both N-nitroso derivatives is NADPH-dependent, requires molecular oxygen, and is inhibited by common inhibitors of microsomal enzyme activities.
