Zinc was found to enhance absorption of free and "peptide" L-tryptophan across the chick mucosal brush border. Intestinal absorption of free L-tryptophan can be partially inhibited by excessive amount of zinc. The findings suggest that zinc interacts with free and "peptide" L-tryptophan transports protecting them against degradation.
