L-tyrosine (Tyr), an important nutritional essential amino acid, plays an important role in human and animal metabolism, growth and development. It is widely used in food, feed, medicine, chemical industry and other industries. It is often used as a nutritional supplement for patients with phenylketonuria and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid and p-hydroxystyrene. As more high value-added L-tyrosine derivatives such as Danshensu, resveratrol and hydroxytyrosol are found in organisms, L-tyrosine is developing towards platform compounds.
