Abstract
PL-Phenylalanine and L- tyrosine were administered by mouth to 3 scorbutic children and the excretion in the urine and the plasma levels of these and other amino acids were determined. Both with and without additional tyrosine the excretion of tyrosine was much higher than by normal children. Since the plasma levels of phenylalanine and tyrosine were low, the amino aciduria was probably of renal origin.Keywords
