Tyrosine Reddit Powder(L - tyrosine, Tyr), it is an essential amino acids, which is a kind of important nutrition for human and animal metabolism, growth and development plays an important role, could be widely used in food, feed, and chemical industry, etc.
It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds.
Tyrosine (Tyrosine, abbreviated as Tyr or Y)[1] or 4-hydroxyphenylalanine, is one of the 22 amino acids used by cells to synthesize proteins. It can be used to synthesize proteins in cells, and its codon is UAC And UAU are non-essential amino acids that contain polar side groups and can be synthesized by the human body. The word "tyrosine" comes from the Greek tyros, meaning cheese. At the beginning of the 19th century, it was first discovered in cheese casein by the German chemist Justus von Liebig,when it is used as a functional group or a side group, it is called tyrosyl.
Tyrosine, an aromatic amino acid, exists in various proteins, especially abundant in milk casein.
1.Tyrosine protects the skin from harmful UV light rays.
2.Besides being a protein amino acid, tyrosine has a special role in signal transduction in proteins by virtue of its phenolic function, which functions as a receptor for phosphate groups transferred by protein kinases (so-called tyrosine kinase receptors) , while phosphorylation of hydroxyl groups alters the activity of the target protein.
3. Tyrosine also plays an important role in photosynthesis. In chloroplasts (photosystem II), it is used as an electron donor in the reduction reaction of oxidized chlorophyll, allowing it to deprotonate the phenolic OH-group, and finally in Photosystem II is reduced by four core manganese clusters.
1.Solid beverage, liquid beverage, dairy products, beauty products, functional food, etc., etc., but not include infant supplies.
2.amino acid drugs.
Raw material for amino acid infusion and amino acid compound preparation, used as nutritional supplement. For the treatment of polio and tuberculous encephalitis / hyperthyroidism and other diseases.
3.nutritional supplements.
After co-heating with sugars, the aminocarbonyl reaction can produce special aroma substances. It is used medicinally to treat hyperthyroidism.
4.It is used in biochemical research, and used as amino acid nutritional medicine in medicine to treat polio, encephalitis, hyperthyroidism and other diseases.
5.Biochemical reagents, APIs.
Belongs to human non-essential amino acids.
6. Available for tissue culture (L-tyrosine·2Na·H2O), biochemical reagents, and treatment of hyperthyroidism. It can also be used as a preparation for the elderly, children's food and plant foliar nutrients, etc.
