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. |
