L-Tyrosine Powder Usage and Synthesis.

The study of tyrosine metabolism helps to understand the pathological process of certain diseases.

Such as urinary black acid disease and tyrosine metabolism disorder, the patient's body lacks urinary black acid oxidase and lead to tyrosine metabolite urinary black acid can not continue to decompose, from the urine discharge in the air oxidised into black material, suffering from this disease children's nappies exposed to the air will gradually become black, this urine will also become black after a long time.

Albinism is also related to tyrosine metabolism, the patient lacks tyrosinase and the tyrosine metabolite 3,4-dihydroxyphenylalanine can not form melanin so that the hair and skin are white.

Uses and functions of L-Tyrosine.

Biochemical studies. Standards for the determination of nitrogen in amino acids. Preparation of tissue culture media. Colorimetric quantitative analysis by Miron reaction (protein colouring reaction). The main raw material for the synthesis of many peptide hormones, antibiotics and other drugs.

Amino acid precursor of dopamine and catecholamine.

Nutritional supplements. After the aminocarbonyl reaction with sugar co-heating, it can generate special flavour substances. Used in medicine to treat hyperthyroidism.

Amino acid drugs. Raw materials for amino acid infusion and amino acid compound preparation, as nutritional supplements. Used in the treatment of poliomyelitis and tuberculous encephalitis/hyperthyroidism.

Characteristic of L-Tyrosine.

White needle crystal or crystalline powder, odourless, bitter taste, mp334℃ (decomposition) insoluble in water (0.04%, 25℃), insoluble in anhydrous ethanol, ether and acetone, soluble in dilute acid or dilute alkali. Isoelectric point 5.66.

Product Method of  Bulk L-Tyrosine Powder.

By casein, sericin and other proteins acid hydrolysate neutralisation of the precipitate produced by the separation, dissolved in dilute ammonia, neutralised with acetic acid to pH = 5, recrystallised and obtained. The pig hair hydrolysate extracted cystine of the second crude crystalline pure liquid, stored at 20 ℃ for two days, so that the tyrosine precipitation, filtration, can be obtained tyrosine crude, can also be obtained by refining L-tyrosine. The yield of pig hair is 1%.
