Glucose as raw material, obtained by fermentation of Brevibacterium departure induced l-tyrosine production;
The tyrosine is the tyrosinase monophenolase function of the catalytic substrate is ultimately the formation of the main raw material of the excellent melanin and pheomelanin. Whitening cosmetic research study Synthesis and tyrosine competition, tyrosinase structural analogs can also can effectively suppress the generation of the melanin.
Vitiligo patients eat foods containing tyrosine can promote the formation of melanin, reduce the symptoms of vitiligo.
Other:
1 It is medicine for hyperthyroidism and food additives.
2 It is an important biochemical reagents, is the main raw material of synthetic polypeptides, hormones, antibiotics, L-dopa and other drugs.
3 It is widely used in agriculture research, but also for beverage additives and the preparation of artificial insects feed.
