Metabolic oxidation of carbon -nitrogen, carbon oxygen and carbon - sulphur systems principally Involves two basic types of bio-transformation processes
(P) Hydroxylation of the α-carbon atom attached directly to the heteroatom
(Q) Mixed function oxidase system also oxidizes carbon atom adjacent to carbonyl and imino functions
(R) Hydroxylation of the hetero-atom only
(S) Microsomal hydroxylation at allylic carbonatom
