Radioimmunoassay and other methods for trace analysis of ,-oxide compoundsde of a tertiary aliphatic amine such as trimethylamine, or tertiary arylalkylamine such as dimethylphenylamine, or heteroaromatic amine such as pyridine or quinoline. The first two types are referred to here as aliphatic tertiary amines. It is established that there are chemical and metabolic diffe

Mechanism, multiple forms and substrate specificities of flavin-containing mono-oxygenasestionally versatile molecule that in different microenvironments carries out a variety of different biological redox functions. Most of these are well known and the present discussion will be restricted to a subgroup of flavin-dependent mono-oxygenases that catalyse the oxidation of an exceptionally

As is the case with the other major monooxygenase system, the cytochrome .-450-dependent mixed-function oxidase, FMO is found in highest concentration in liver and requires NADPH and 0. for activity. However, unlike the .-450 system, mammalian FMO is not inducible by phenobarbital, 3

Products of the oxidation of different amines include hydroxylamines, .-oxides, pyridines, dealkylation products and other compounds. A proper understanding of the catalytic mechanism of .-450 is important

Much attention has been focused on the .-oxidation of arylamines and arylamides by cytochrome .-450-dependent hepatic mixed function oxidases. However, peroxidases (donor-H.O. oxidoreductases, EC 1.11.1.7) als
