L-Phenylalanine is colorless to white flaky crystal or white crystalline powder. Slightly special smell and bitterness. Melt at about 283 ° C and decompose. The 10% aqueous solution has a pH of 5.4 to 6.0. In the heat, light, air stable. Coloring with heating with glucose. Under alkaline instability. Dissolved in water (3g / 100ml, 25 ° C). Insoluble in ethanol, dilute mineral acids and alkaline solution.
L- Phenylalanine used for biochemical research, preparation of culture medium, medicine for amino acid nutrition medicine. For amino acid infusion, amino acid preparations and nutrition fortifier. Nutritional supplements. One of the essential amino acids. Almost non-limiting amino acids in most food proteins. Can be added to baked goods, in addition to strengthening phenylalanine, and carbohydrates from amino-carbonyl reaction, can improve the flavor of food. Can also be used to formulate amino acid infusion and integrated amino acid preparations,it is a two peptide sweet raw material.
