Selective ion monitoring of tryptophan, N-acetyltryptophan and kynurenine in human serum. Application to the in vivo measurement of tryptophan pyrrolase activity.
Wegmann H, Curtius HC, Redweik U. Wegmann H, et al. J Chromatogr. 1978 Oct 1;158:305-12. doi: 10.1016/s0021-9673(00)89975-6. J Chromatogr. 1978. PMID: 721934
A specific method is described for the determination of deuterated and non-deuterated N-acetyltryptophan, tryptophan and kynurenine in human serum and urine using gas chromatography-mass fragmentography. N-Acetyltryptophan was analysed as the N-trimeth …
