Structure reactivity analysis for Phenylalanine and Tyrosine

open access: yesCumhuriyet Science Journal, 2021
Phenylalanine (Phe) is one of the amino acids that cannot be produced in the body and must be ingested through diet. Tyrosine (Tyr) is also a non-essential amino acid and can be produced by Phe hydroxylation in the liver when the dietary intake of Tyr is
