Abstract:
The free amino acid concentrations in serum were determined in 65 normal adults by use of the physiological fluid analysis in Hitachi 835-50 Model Amino Acid Autoanalyer. 29 specimens were determined by physiological fluid analysis and protein hydrolyzate analysis method simultaneous-ly.The results of Serine, Glycine, Valine, Isoleucine, Leucine, Tyrosine, Phenylalanine, Lysine, Tryptophan, Proline, and the molar ratio of the bran-ched-chain amino acids/aromatic amino acids were very similar. By hy-drolyzate method Aspartic acid was not detected and Threonine, Glutmic acid, Cystine, Methionine and Arginine were higher than physiological fluid analysis.The reasons for such higher values were discussed.
