Uses and synthesis of L-Phenylalanine powder

L-Phenylalanine powder is a colourless to white flaky crystal or white crystalline powder, L-Phenylalanine CAS 63-91-2 is a nutritional supplement, is one of the essential amino acids.

In the body, most of it is oxidised to tyrosine by the catalysis of phenylalanine hydroxylase, and together with tyrosine it synthesises important neurotransmitters and hormones, and participates in the body's sugar metabolism and fat metabolism.

Applications / Functions of L-Phenylalanine powder

Nutritional supplement. One of the essential amino acids. L-Phenylalanine powder can be added to baked goods, in addition to fortifying phenylalanine, can improve the aroma of food by reacting with sugar in an aminocarbonyl group. L-Phenylalanine powder can also be used in the preparation of amino acid infusion and comprehensive amino acid preparations.

1. L-Phenylalanine CAS 63-91-2 is one of the essential amino acids and can be used as amino acid raw material medicine. It is mainly used in functional food additives as a nutrient fortifier, amino acid infusion and as a component of complex amino acid preparations.
2. L-Phenylalanine Raw Materials is the raw material of many kinds of anticancer drugs and dipeptide sweetness, used in biochemical research, the preparation of culture medium, and used as amino acid nutritional drugs in medicine.

Physicochemical Property of L-Phenylalanine powder

Colourless to white flaky crystal or white crystalline powder. Slightly special odour and bitter taste. Melts and decomposes at about 283°C. The pH value of 10% aqueous solution is 5.4-6.0. It is stable in heat, light and air.

L-Phenylalanine powder is coloured when heated with glucose. Unstable under alkaline. Soluble in water (3g/100ml, 25℃). Difficult to dissolve in ethanol, dilute inorganic acid and alkaline solution.

Production methodprocess of L-Phenylalanine powder

L-Phenylalanine CAS 63-91-2 is obtained by reacting with 2,5-dibromobenzenesulfonic acid as raw material, crystallising at 0°C to obtain the crude product, and then recrystallising and refining with a hot solution of ethylene glycol, methyl ether and water.

After hydrolysis of defatted soybean with hydrochloric acid, acidic amino acid is removed, and phenylalanine, tyrosine and pigment are adsorbed with activated carbon or decolourising resin, then phenylalanine is dissolved and L-Phenylalanine Raw Materials is obtained by isolation. L-Phenylalanine powder can also be separated from hydrolysate by forming 2,5-dibromophenyl sulfonate, which is insoluble in water, and then separated from leucine and arginine by taking advantage of the difference in solubility.
