L-Tyrosine CAS NO.60-18-4

It is an important nutrient essential amino acid, which plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, medicine and chemical 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 peptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, hydroxytyrosol, etc. are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds.
