title: Organophosphorus compounds. II. Metabolic considerations.
abstract: Organophosphorus compounds are esters of alcohols with phosphoric acids or anhydrides of phosphoric acids with some other acids. The most important groups are the phosphates, phosphorothionates, phosphorothioates, phosphoroamidates, phosphorochloridate and phosphonates. The metabolism of phosphorothionates and phosphorothioates involves initial activation (oxidative desulphuration) followed by hydrolysis of the active metabolites. Activation is carried out by the action of microsomal oxidases, and degradation is performed by different types of hepatic and plasma esterases.
