Tyrosine (tyrosine; Tyr) chemical name is 2 - amino - 3 - hydroxy phenyl propionic acid, it is a kind of aromatic polarity.alpha.-amino acid containing phenol hydroxyl. Tyrosine is human body essential amino acids and the conditions of ketogenic raw sugar amino acids  Tyrosine is Li Biqi from casein, found in 1846 as a white crystalline powder, the crystallization of needle or flake from the water body. Relative density 1.456 (20 ºC), isoelectric point 5.66, the uv absorption ability, had the largest in the wavelength of 274 nm light absorption, can restore phosphomolybdic acid - phosphotungstic acid reagent (the forint reagent). Melting point: left-handed body of 290 ~ 295 ºC when the decomposition (slow heating), 314 ~ 318 ºC when the decomposition (rapid heating), racemic form decomposition (slow heating) 290 ~ 295, 340 ºC decomposition (rapid heating). Soluble in water, ethanol, acid and alkali, insoluble in ether. The aqueous solution of the dextrons is shown in red when interacting with tyrosinase. Sinistral physical friction, with barium hydroxide aqueous solution at 170 ºC heating into racemic form, phenolic group of tyrosine molecular ortho used biochemical reaction, with diazo benzene sulfonic acid coupling funai) material, and boiling dilute acetic acid and sodium nitrite in purple or red, with warm yellow, nitrate and titanium dioxide in sulfate in dark orange. Natural tyrosine as a left-handed, can be made of protein hydrolysis, refined but

Tyrosine is a non-essential amino acid that regulates mood and stimulates the nervous system. It also helps to speed up the body's metabolism and treat conditions such as chronic fatigueTyrosine is single phenol enzyme catalytic tyrosinase substrate, is the ultimate formation of melanin and pheomelanin main raw material. In the research and development of whitening cosmetics, can through the study of tyrosinase structure synthesis competition with tyrosine analogues can effectively inhibit the formation of melanin.
1. Amino acids. Amino acid infusion and amino acid compound preparation of raw materials, as a nutritional supplement. It is used in the treatment of diseases such as polio and tuberculous encephalitis/hyperthyroidism. 2. Nutritional supplements. It is used medicinally to treat myelitis and tuberculous encephalitis, hyperthyroidism and other diseases, and also to make L-dopa diiodotyrosine. After co-heating with saccharides, the amino-carbonyl reaction can produce special flavor substances.
3. Used for biochemical research, medicine, used for amino acids nutrition medicine, treatment of diseases such as polio, encephalitis, hyperthyroidism.
4. Biochemical reagents and raw materials. Non-essential amino acids belongs to the human body.
5. Available for tissue culture (L-tyrosine·2Na·H2O), biochemical reagents, treatment of hyperthyroidism. It can also be used as a compound for the aged, children's food and plant foliar nutrition
