Tyrosine powder Introduction

Tyrosine is an amino acid that constitutes a protein. It has an ionized aromatic ring side chain and is hydrophilic. Tyrosine is produced by hydroxylation of phenylalanine in humans and animals. Therefore, when phenylalanine is adequately nutritious, it is non- Essential amino acids.
The catabolism of tyrosine is first converted to p-hydroxyphenylpyruvate catalyzed by intrahepatic tyrosine transaminase, which requires pyridoxal phosphate as a coenzyme. The action of p-hydroxyphenylpyruvate via p-hydroxyphenylpyruvate hydroxylase simultaneously causes oxidative decarboxylation and transfer of side chain pyruvate and hydroxylation of the ortho position of the phenyl ring to form homogentisic acid (dihydroxyphenylacetic acid). The enzyme is a copper-containing metalloprotein that requires ascorbic acid to act as a coenzyme and consume molecular oxygen. Uroic acid is catalyzed by urinary acid dioxygenase (uric acid oxidase) to split the benzene ring to produce maleic acetoacetic acid; the enzyme is an iron-containing metalloprotein, and the reaction requires one molecule of oxygen to participate. . Maleic acetoacetic acid is converted to fumaric acid by the action of the corresponding isomerase, and glutathione is required as a coenzyme. Finally, it is hydrolyzed to fumaric acid and acetoacetic acid by the corresponding hydrolase, so tyrosine is both a raw sugar and a ketone amino acid.
Tyrosine powder Function

1.i Tyrosine is Nutritional supplements. It is used in medicine for the treatment of myelitis and tuberculous encephalitis, thyroid hyperthyroidism, and also for the production of L-dopa diiodotyrosine. When an aminocarbonyl group is reacted with a saccharide, a special aroma substance can be formed.

2.i Tyrosine is used in Biochemical research. The standard for determining nitrogen in amino acids. Tissue culture medium was prepared. Colorimetric quantitative analysis was carried out using a Millon reaction (protein color reaction). It is the main raw material for the synthesis of a variety of peptide hormones, antibiotics and other drugs, amino acid precursors of dopamine and catecholamines.
