| L-Phenylalanine Usage And Synthesis |
| Chemical Properties | White crystalline powder |
| Usage | L-Phenylalanine is an essential amino acid. L-Phenylalanine is biologically converted into L-tyrosine, another one of the DNA-encoded amino acids, which in turn is converted to L-DOPA and further conv erted into dopamine, norepinephrine, and epinephrine. L-Phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of Aspartame. |
| General Description | Odorless white crystalline powder. Slightly bitter taste. pH (1% aqueous solution) 5.4 to 6. |
| Air & Water Reactions | Water soluble. Aqueous solutions are weak acids. |
| Reactivity Profile | L-Phenylalanine may be light sensitive. Act as weak acids in solution. |
| Health Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition L-Phenylalanine emits toxic fumes of nitrogen oxides. |
| Fire Hazard | Flash point data for L-Phenylalanine are not available; however, L-Phenylalanine is probably combustible. |
