Indolic tryptophan metabolism in uraemia

Abstract:
Tryptophan and some indolic metabolites were studied in urine, plasma and dialysate of uraemic patients using thin-layer- and high-pressure liquid chromatography. Some new metabolites: indole-3-carboxylic acid, indole-3-carbaldehyde, indolelactic acid and N-acetyltryptophan were detected. Levels of the latter two metabolites in urine, dialysate and especially plasma suggest increased transamination of tryptophan and a possible defect in renal amino acid acylase in uraemia.
