## Abstract Two labeled isotopomers of L‐tyrosine, L‐Tyr, have been synthesized using specific properties of the enzymes phenylanine ammonia lyase, PAL, and L‐phenylalanine hydroxylase. In an intermediate step [1‐^14^C]‐, and [2‐^14^C]‐L‐phenylalanine, L‐Phe, have been obtained from [1‐^14^C]‐, and
