Results will be reported as “Tryptophan as Dehydrate” to signify that the reported value for the individual amino acid does not include the molecular weight of water. If you are in need of the hydrated tryptophan value (individual amino acid that includes the molecular weight of one water molecule) please let us know at the time of sample submission.
The sample is run through an alkaline digestion and reverse-phase chromatography for Tryptophan determination.
