Effect of ascrobic acid on carcinogenicity of p-hydroxyphenyl-lactic acid

Interest in ascorbic acid as a supplementary agent with a positive effect in the treatment of cancer has increased considerably in the last decade. Ascorbic acid has been shown to have a distinct inhibitory effect on carcinogenesis induced in experimental animals by precursors of nitrosamines [7], by preventing the formation of carcinogens from them by metabolitesof tryptophan and tyrosine [3, 8], an effect primarily linked with the properties .of ascorbic acid as an active antioxidant [6], or explained by the specific participation of this vitamin in the metabolism of these amino acids.
