White needle crystalls or crystal powder, odourless, taste bitter, mp334 ℃ (decomposition) poorly soluble in water (0.04%, 25 ℃), insoluble in ethanol, ether and acetone, soluble in dilute acid or dilute alkali. The isoelectric point is 5.66.
Amino acids. The raw materials of amino acid infusion and amino acid compound preparation are used as nutritional supplements. For the treatment of poliomyelitis and tuberculous encephalitis/hyperthyroidism and other diseases.
Nutritional supplements.
After co-heating with saccharide, amino carbonyl reaction can be produced, which can produce special flavor substance.
Medicine used to treat hyperthyroidism.
It is used in biochemical research and is used as amino acid nutrition medicine in medicine to treat diseases such as poliomyelitis, encephalitis and hyperthyroidism.
Nutritional supplements. It is used medicinally in the treatment of myelitis, tuberculosis encephalitis, hyperthyroidism, etc. It is also used in the production of l-dopa diiodotyrosine. After co-heating with saccharide, amino carbonyl reaction can be produced, which can produce special flavor substance.
Biochemical reagents, raw materials. It is a non-essential amino acid of human body.
Available for tissue culture (l-tyrosine ·2Na·H2O), biochemical reagent and treatment of hyperthyroidism. Can also be used as a preparation of elderly, children's food and plant leaf nutrition agents
Biochemical research. Standard for the determination of nitrogen in amino acids. Tissue culture medium was prepared. Colorimetric quantitative analysis was carried out by millon reaction (color reaction of protein). It is the main raw material for the synthesis of various peptide hormones, antibiotics and other drugs, and the amino acid precursor of dopamine and catecholamines.
