Tyrosinase is a copper-containing enzyme that catalyzes the oxidation of tyrosine and polyphenolic compounds, and is involved in various metabolic processes in organisms. Tyrosinase is widely distributed in animals and plants. In animals, tyrosinase is involved in the synthesis of melanin, a pigment component of skin, hair and eyes. In plants, tyrosinase is involved in the synthesis of polyphenolic compounds and defense responses against pathogens and environmental stress. The importance of tyrosinase in various biological processes has led to its widespread application in food processing, cosmetics and medicine. In the food industry, tyrosinase is used to improve the flavor and color of fruits and vegetables, and to produce fermented foods such as cheese and wine. In the cosmetic industry, tyrosinase inhibitors are used to whiten the skin and reduce the appearance of age spots and freckles. In the medical field, tyrosinase is used as a target for the treatment of melanoma, a skin cancer caused by abnormal proliferation of melanocytes. In summary, tyrosinase is a multifunctional enzyme that plays an important role in animal and plant metabolism. Its catalytic activity and biological functions make it a valuable tool for research and application in various fields
