Usage And Synthesis
Tyrosine

Tyrosine is an aromatic amino acid , can be found in a variety of proteins, and is particularly rich in casein milk protein, molecules containing phenoll groups, Its structural formulais is as follows:

Tyrosine is found by Li Biqi 1846 from casein, white crystalline powder, needle-like crystals or platelets from the water. The relative density of 1.456 (20 ºC), the isoelectric point of 5.66, UV absorption capacity, at a wavelength of 274nm of maximum light absorption, capable of reducing phosphomolybdic acid-phosphotungstic acid reagent (Folin reagent). Melting point: L-body decomposition 290~295 ºC (slow heating), decomposition (rapid heating) 314~318 ºC, the racemate 290 to 295 decomposition (slow heating), decomposition (rapid heating) 340 ºC. Soluble in water, alcohol, acid and alkali, insoluble in ether. Dextrose solution reacts with tyrosinase to be red. laevo isomer friction can emit light , when at 170 ºC heated with the barium hydroxidde solution ,it can become a racemate, ortho of the phenoollic hydroxyl group of tyrosine molecule is prone to chemical reaction, when coupled with a diazonium acid ,it is orange-red substance, when coupled with boiling dilute acetic acid and sodium nitritte ,it is purple or red, yellow when coupled with nitricc acid, when in sulfuric acid reacting with titanium dioxide it is dark orange. L-tyrosine is a natural body, by proteolysis, refining.
