Free Amino Acids in the Brain

4 Aromatic Amino Acids in the Brain

This chapter describes the aromatic L‐amino acids tryptophan and tyrosine and the effects on tyrosine metabolism of phenylalanine. Tryptophan and phenylalanine are essential amino acids and must ultimately be derived from dietary proteins; tyrosine is obtained both from dietary proteins and from the hydroxylation of phenylalanine by phenylalanine hydroxylase (PAH). The proportions of dietary tr...

Contents of Free Amino Acids in Mushrooms

The fruit bodies of 113 kinds of mushrooms were examined by amino acid analyzer to determine 20 free types of protein amino acids and 11 non-protein amino acids . (1) Though considerable difference was often found among species of mushroom, the average of total free amino acids was 213μ mol/g dry matter. (2) It was found that the amount of alanine, glutamic acid and glutamine was very high and ...
