Product Description

What Is L-tyrosine ?

The chemical name of tyrosine (Tyr) is 2-amino-3-p-hydroxyphenylpropionic acid, which is an aromatic polar α-amino acid containing a phenolic hydroxyl group. Tyrosine is a conditional essential amino acid and a ketogenic sugar-generating amino acid for the human body. It is soluble in water, ethanol, acid and alkali, but insoluble in ether. The aqueous solution of dextran and tyrosinase show a red color. The levorotatory body can be rubbed and emits light, and it is transformed into a racemic body by heating with barium hydroxide aqueous solution at 170°C.

Function Of L-tyrosine

L-tyrosine is the catalytic substrate for the monophenolic function of tyrosinase and the main raw material for the final formation of eumelanin and pheomelanin. In the research and development of whitening cosmetics, the synthesis of tyrosinase structural analogues that compete with tyrosine can also effectively inhibit the production of melanin. Patients with vitiligo eating foods containing L-tyrosine can promote the formation of melanin and reduce the symptoms of vitiligo. L-tyrosine is the raw material for amino acid infusion and amino acid compound preparations, and is used as a nutritional supplement. Treatment of polio, nuclear encephalitis, and hyperthyroidism. It is also used as a raw material for the manufacture of diiodotyrosine, dibromotyrosine and L-dopa.

A typical dose of L-tyrosine is about 1 to 2 grams per day. As an antidepressant, take 500 to 1,000 mg two to three times a day. Because L-tyrosine has a stimulating and anti-depressant effect, 1000 to 1500 mg tryptophan (tryptophan calms people) taken in the morning and before lunch will have a good therapeutic effect on reducing depression at night . Researchers have found that for some people, tryptophan and tyrosine used together, than tyrosine or tryptophan alone, are more effective in reducing depression.

Application Of L-tyrosine

1. Amino acid drugs. The raw material of amino acid infusion and amino acid compound preparation, used as nutritional supplement. It is used to treat polio and tuberculous encephalitis/hyperthyroidism. 2. Nutritional supplements. It is used in medicine to treat myelitis, tuberculosis encephalitis, hyperthyroidism and other diseases. It is also used to manufacture L-dopa diiodotyrosine. After co-heating with sugars, the amino carbonyl reacts to produce special flavor substances. 3. Used in biochemical research, used as amino acid nutrition medicine in medicine to treat polio, encephalitis, hyperthyroidism and other diseases. 4. Biochemical reagents, bulk drugs. It is a non-essential amino acid. 5. It can be used for tissue culture (L-tyrosine·2Na·H2O), biochemical reagents, and treatment of hyperthyroidism. It can also be used to modulate food for the elderly, children, and plant leaf nutrition, etc.
