Product Description:
L-Tyrosine is the catalytic substrate for the monophenolase function of tyrosinase and is the main raw material for the final formation of eumelanin and pheomelanin. In the research and development of whitening cosmetics, it is possible to effectively inhibit the production of melanin by studying the synthesis of tyrosinase structural analogues that compete with tyrosine.
Vitiligo patients eat foods containing tyrosine can promote the formation of melanin and reduce the symptoms of vitiligo.
Amino acid infusion and amino acid compound preparation raw material, used as nutritional supplements. Treatment of polio and nuclear encephalitis, hyperthyroidism and other diseases. It is also used as a raw material for the manufacture of diiodotyrosine,dibromotyrosine and L-dopa.
