Determination of Tryptophan and Tryptophan Metabolites in Grape Must and Wine

1999
Tryptophan (Trp) and its metabolites, especially indole-3-acetic acid (IAA), are considered as potential precursors of 2-aminoacetophenone (AAP), an aroma compound which causes the "untypical aging off-flavor" (UTA) in Vitis vinifera white wines. In this study RP-HPLC with fluorescence detection was used for the qualitative and quantitative analysis of

Excretion of Tryptophan Metabolites after Physical Effort

Nature, 1961
IT has been shown that muscular effort is accompanied by the increased urinary excretion of one of the metabolites of tryptophan, namely, indoleacetic acid1. Pelikan and co-workers2 have proved that there is increased excretion of another tryptophan metabolite, xanthurenic acid, after muscular effort.

Tryptophan Metabolites: A Microbial Perspective

2015
The discovery of the regulation of tryptophan biosynthetic pathway by means of a repressible operon has been recognised as a milestone in genetics. This long multistep pathway is energetically so expensive that numerous allosteric control loops exist in addition to tight genetic regulation.

Role of Tryptophan Metabolites in Urinary Bladder Cancer

American Industrial Hygiene Association Journal, 1969
Abstract Evidence from clinical and experimental studies suggests that certain urinary tryptophan metabolites may play a role in human bladder carcinogenesis. Five metabolites of this essential amino acid—kynurenic acid, acetyl-L-kynurenine, L-kynurenine, 3-hydroxy-L-kynurenine, and 3-hydroxyanthranilic acid—were reported as occurring in elevated ...
