Methylglyoxal-derived beta-carbolines formed from tryptophan and its derivates in the Maillard reaction.
Reaction of tryptophan, tryptophan methyl ester and tryptamine with methylglyoxal (a physiological alpha-oxoaldehyde), which resulted in beta-carboline formation, showed that this type of nonenzymatic (Maillard) reaction could spontaneously occur in living organisms or during commercial or domestic food processing and storage.
