Tyrosine Pure is a fragrant amino acid that exists in various proteins, specifically rich in milk casein. It consists of a phenol group in its particle and also its architectural formula is:

Tyrosine Pure was discovered by Li Biqi from casein in 1846. It is a white crystalline powder that takes shape right into needles or flakes from water. The family member density is 1.456 (20 ° C), the isoelectric factor is 5.66, as well as it has the ability to absorb ultraviolet rays. It has the optimum light absorption at the wavelength of 274nm, and also can minimize phosphomolybdic acid-phosphotungstic acid reagent (Folin reagent). Melting point: Levorotatory body decays at 290-295 ° C(slow-moving home heating), 314-318 ° C(fast heating), racemic body decays at 290-295 (slow-moving home heating), 340 ° C(quick home heating). Soluble in water, ethanol, acid as well as antacids, insoluble in ether. The aqueous option of D-isomer responds with tyrosinase as well as reddens. The left-handed body can triboluminescence, and it can be transformed right into a racemate when heated with barium hydroxide liquid service at 170 ° C. The ortho-position of the phenolic hydroxyl team in the tyrosine molecule is prone to chemical reactions, and it is paired with diazobenzenesulfonic acid to acquire an orange-red compound, which works with boiling The activity of thin down acetic acid and salt nitrite is purple or red, the activity of warm nitric acid is yellow, and the action of titanium dioxide in sulfuric acid is dark orange yellow. All-natural tyrosine is a left-handed body, which can be gotten by hydrolyzing as well as refining proteins.
Tyrosine Pure is a non-essential amino acid, which is a basic material for numerous body items. Tyrosine can be converted into numerous physical materials through different metabolic paths in the body, such as dopamine, adrenaline, thyroxine, melanin and poppy (opium) of papaverine. These materials are closely related to the control of nerve conduction and metabolic guideline. Studying tyrosine metabolism assists to understand the pathological procedure of particular illness. As an example, alkapsis is connected to tyrosine metabolism problem. The absence of alkapsis oxidase in the body of the client triggers the metabolite of tyrosine, alkapsis, to stop working to decay, and it is excreted from the urine and also oxidized into a black compound airborne. Kid’s diapers will slowly turn black when subjected to the air, and the pee will likewise transform black after a long time. Albinism is additionally associated with the metabolic rate of Tyrosine Pure. People lack tyrosinase to ensure that the tyrosine metabolite 3,4-dihydroxyphenylalanine can not develop melanin, to ensure that the hair and also skin are white.
