Gas chromatographic analysis of urinary tyrosine and phenylalanine metabolites in patients with gastrointestinal disorders

By C. van der Heiden, E.A.K. Wauters and D. Ketting


Main urinary bacterial metabolites of phenylalanine (total benzoic and phenylacetic acids) and of tyrosine (total p-hydroxybenzoic acid and p-hydroxyphenylacetic acid) were determined by gas chromatography in controls and patients with cystic ubrosis of the pancreas, coeliac disease, intestinal resection and unclassified enteritis.

In this paper results in controls and patients are presented and discussed
