Uses
Important intermediates: intermediates of derivative products of L-tyrosine series, including 3,4-dihydroxy-L-phenylalanine (L-DOPA), melanin, coumaric acid, etc., are not only widely used in medicine, chemical industry and other fields, but also raw materials of various chemical products. L-DOPA is an effective drug for Parkinson's disease; The physicochemical properties of melanin enable it to be used as an ultraviolet absorber, cation exchanger, drug carrier, etc; Coumaric acid is an important component of some novel complexes, coatings and adhesives.
Amino acid drugs and nutritional supplements: L-tyrosine is the raw material of amino acid infusion and amino acid compound preparation as a nutritional supplement. It is used to treat poliomyelitis and tuberculous encephalitis/hyperthyroidism.
