Summary The effect of five amino acids ( L -tryptophan, L -cysteine, L -methionine, L -tyrosine and L -glycine) on liver nitrosodimethylamine-demethylase activity was studied. Each amino acid was fed at a level of 1% of the diet to weanling male Wistar rats for 12 days. Tryptophan increased the enzyme activity and cysteine had the opposite effect. The other amino acids tested had no effect. When the effect of the duration of the tryptophan feeding (3–47 days) and the age of the animals (21–51… Expand
