Molecular formul | C9H11NO2 |
| Molecular weight | 165.19 |
| Purity | 98.5%min L-Phenyalanine |
L-Phenylalanine is an essential amino acid that cannot be synthesized by the human body. Almost non-limiting amino acid in the proteins of most foods. Colorless to white flaky crystals or white crystalline powder. Slightly special odor and bitter taste. Stable in heat, light and air. Difficult to dissolve in ethanol, dilute inorganic acids and alkaline solutions.Physiological effects of L-phenylalanine are related to tyrosine. Can affect thyroid hormone and melanin of hair and skin.D phenylalanine has the same physiological effect as L phenylalanine.

Function and Application:
1. L-Phenylalanine can be added to baked goods, in addition to strengthening phenylalanine, and sugar amino-carbonyl reaction, can be used to improve the flavor of food.
2. L-Phenylalanine powder is mainly used as the synthetic raw material of food sweetener aspartame in food industry; L-phenylalanine food grade can also be used as nutritional supplements.
3. L Phenylalanine can be used as nutritional supplements. Refined Pharmacopoeia Grade L Phenylalanine is mainly used in the pharmaceutical industry for amino acid infusion and amino acid drugs. Pharmaceutical grade L-phenylalanine powder can be made into L-phenylalanine capsules.
4. L-Phenylalanine can be used in biochemical research. phenylalanine powder can be used to prepare culture media.
5. L-Phenylalanine is used as a component of nutrient fortification, amino acid infusion and compound amino acid preparation. It is the raw material of many kinds of anticancer drugs and dipeptide sweet flavor.
