WebTryptophan (Trp) is a difficult amino acid to determine in proteins and peptides because it chemically decomposes during acid hydrolysis. Consequently, many procedures have been developed for the indepen-dent preservation and determination of this amino acid. Mercaptan antioxidants such as thioglycolic acid, thiodiglycolic acid, or ... WebJan 27, 2024 · Abstract. The kynurenine pathway, in which tryptophan is metabolized to kynurenine and kynurenic acid, has been linked to depression. A rapid and highly reproducible liquid-chromatography-tandem mass spectrometry (LC-MS/MS) method were established for determining tryptophan, kynurenine and kynurenic acid in human serum.
