Tyrosine is a non-essential amino acid, which is a raw material for various products in the body. Tyrosine can be converted into various physiological substances through different metabolic pathways in the body, such as dopamine, adrenaline, thyroxine, melanin and opium poppy (opium). ) of papaverine. These substances are closely related to the control of nerve conduction and metabolic regulation. Studying tyrosine metabolism helps to understand the pathological process of certain diseases. For example, alkapsis is related to tyrosine metabolism disorder. The lack of alkapsis oxidase in the body of the patient causes the metabolite of tyrosine, alkapsis, to fail to decompose, and it is excreted from the urine and oxidized into a black substance in the air. Children's diapers will gradually turn black when exposed to the air, and the urine will also turn black after a long time. Albinism is also related to the metabolism of tyrosine. Patients lack tyrosinase so that the tyrosine metabolite 3,4-dihydroxyphenylalanine cannot form melanin, so the hair and skin are white.

1. Amino acid drugs. Raw material for amino acid infusion and amino acid compound preparation, used as nutritional supplement. For the treatment of polio and tuberculous encephalitis / hyperthyroidism and other diseases.
2. Nutritional supplements. After co-heating with sugars, the aminocarbonyl reaction can produce special aroma substances. It is used medicinally to treat hyperthyroidism.
3. Used in biochemical research, and used as amino acid nutritional medicine in medicine to treat polio, encephalitis, hyperthyroidism and other diseases.
4. Biochemical reagents, APIs. Belongs to human non-essential amino acids.
5. Biochemical research. Standard for the determination of nitrogen in amino acids. Prepare tissue culture medium. Colorimetric quantitative analysis was performed using the Mylon reaction (protein color reaction). It is the main raw material for the synthesis of various peptide hormones, antibiotics and other drugs, and the amino acid precursor of dopamine and catecholamine.
