Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization.

Application

N-Acetyl-DL-tryptophan is produced via chemical synthesis using the standard amino acid, tryptophan. It can be used in downstream applications of biopharmaceutical production as a transfer agent or stabilizer.
