Abstract:
:L-tryptophan is an essential amino acid in food, but is also widely used as a drug on the basis of several physiological actions. Lately, tryptophan's uses as a drug and as a food supplement have been discontinued in several countries due to its severe side-effects.In the present study, the distribution of tryptophan in mice was studied with special attention on the target organs, where the drug has been shown to have pathological or physiological effects.The results showed that several organs took up tryptophan and that glucose loading increased the accumulation. An interesting finding was that the highest concentration of tryptophan was found in the pancreas. The hypophysis and adrenal glands were also sites of accumulation. Within the brain the highest accumulation was found in the cerebrum. High concentrations were also seen in the gastrointestinal tract and bone marrow.The connection between the accumulation of tryptophan and its normal and pathophysiological effects is discussed.
