Cytotoxic and mutagenic effects of tobacco-borne free fatty acids.

Abstract excerpt

Tobacco smoke contains substances capable of binding iron in an aqueous medium and transferring the metal into both organic solvents and intact mammalian red cells. This iron-binding activity is due to free fatty acids which are abundant in tobacco smoke and form 2:1 (free fatty acid:iron) chelates with ferrous iron. These earlier observations suggested that smoke-borne free fatty acids and the associated...
