L-Tyrosine

Product introduction:

Co heating with sugars can produce the reaction between amino carbonyls to produce a special flavor. Tyrosine is the catalytic substrate of tyrosinase monophenolase function and the main raw material for the final formation of eumelanin and brown melanin. In the research and development of whitening cosmetics, the synthesis of tyrosinase structural analogues competing with tyrosine can also effectively inhibit the production of melanin. Eating foods containing tyrosine in patients with vitiligo can promote the formation of melanin and reduce the symptoms of vitiligo. The raw material of amino acid infusion and amino acid compound preparation is used as nutritional supplement. Treat poliomyelitis, nuclear encephalitis, hyperthyroidism and other diseases. It is also used as raw material for manufacturing diiodine tyrosine, dibromo tyrosine and L-dopa.
