Tyrosine powder Introduction

L-Tyrosine is the amino acid that makes up protein. The chemical name for tyrosine amino acid is 2-amino-3-p-hydroxyphenylpropionic acid, which is an aromatic polar alpha-amino acid containing a phenolic hydroxyl group. Tyrosine is a conditional essential amino acid and a ketogenic glycogenic amino acid in the human body.

Tyrosine was found in casein by Li Biqi in 1846. It is a white crystalline powder that crystallizes from water into needles or flakes. The relative density of 1.456 (20 ° C), isoelectric point of 5.66, absorbs ultraviolet light, has maximum light absorption at a wavelength of 274 nm, and can reduce phosphomolybdic acid-phosphoric acid reagent (Forint reagent). Melting point: Decomposition of the left-handed body at 290 to 295 ° C (slow heating), decomposition at 314 to 318 ° C (rapid heating), decomposition of the racemate at 290 to 295 (slow heating), decomposition at 340 ° C (rapid heating). Soluble in water, ethanol, acid and alkali, insoluble in ether. The aqueous solution of the right-handed body is reddish with tyrosinase. The left-handed body can rub the luminescence, and it is converted into a racemate with an aqueous solution of cesium hydroxide at 170 ° C. The phenolic hydroxyl group in the tyrosine molecule is chemically reactive, and is coupled with diazonium sulfonic acid to obtain an orange-red substance. The action of dilute acetic acid and sodium nitrite is purple or red, yellow with warm nitric acid, and dark orange-yellow with sulfur dioxide in sulfuric acid. The natural tyrosine is a left-handed body, which can be obtained by hydrolysis and purification of proteins.
