the microsomal metabolism of the carcinogen n-nitrosodimethylamine ( ndma ) was suggested to be initiated by hydrogen atom abstraction to form an alpha-nitrosamino radical , which either oxidizes further to an alpha-hydroxy nitrosamine as the initial product of the activating dealkylation pathway or fragments to the nitric oxide radical and n-methylformaldimine as the first step of the presumably inactivating denitrosation route .
