Abstract

Reactions between L-tryptophan and peroxidizing methyl linoleate in a model system simulating the porous structure of dehydrated foods result in formation of N-formylkynurenine, kynurenine, and diastereomers of dioxindole-3-alanine. A mechanism, consistent with the free-radical pathway for oxidation of polyunsaturated lipids, is proposed for formation of these products from L-tryptophan degradation by peroxidizing lipids.
