Acidic metabolites of phenylalanine in plasma of phenylketonurics.
Seven aromatic metabolites of phenylalanine were determined in plasma of 20 patients with classical phenylketonuria by means of capillary gas chromatography. The results obtained showed good correlation with plasma phenylalanine levels. Plasma aromatic acid levels may prove useful in the diagnosis and management of phenylketonuria, as well as in research of this disorder.
