Abstract
Plasma amino acid concentrations were measured and selected amino acid ratios were calculated in 12 normal adults and 12 adults heterozygous for phenylketonuria (PKU) ingesting a hamburger and milk shake meal providing 1 g protein/kg body wt. Plasma concentrations of all amino acids increased significantly over baseline after meal ingestion in both groups, reaching the highest mean values 3–5 h after meal ingestion. Plasma phenylalanine concentrations were significantly higher in heterozygous than in normal subjects both before and at all times after meal ingestion. The absolute increase in plasma phenylalanine concentration over baseline and the area under the plasma phenylalanine concentration-time curve were approximately twice as large in heterozygous as in normal subjects. However, the molar ratio of the plasma phenylalanine concentration to the sum of the plasma concentrations of the other large neutral amino acids did not increase significantly over baseline, but rather decreased.
