L-tyrosine

Tyrosine (Tyr) is an important nutritional essential amino acid, which plays an important role in the metabolism, growth and development of human and animals. It is widely used in food, feed, medicine and chemical industry. It is often used as a nutritional supplement for patients with phenylketonuria, as well as a raw material for the preparation of peptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, p-hydroxystyrene and other pharmaceutical and chemical products. With the discovery of more high value-added L-tyrosine derivatives such as Danshensu, resveratrol and hydroxytyrosol in vivo, L-tyrosine is becoming more and more platform compounds.
