L-Methionine Usage And Synthesis |
Chemical Properties | White crystalline powder |
Usage | Essential aminoacid for human development. Hepatoprotectant; antidote (acetominophen poisoning); urinary acidifier. |
General Description | Minute hexagonal plates from dilute alcohol. |
Air & Water Reactions | Reacts with water, steam, and/or acids to produce toxic and flammable vapors of hydrogen sulfide . Water soluble . pH of 1% aqueous solution is 5.6-6.0. |
Reactivity Profile | An organosulfide and amine derivative, carboxylic acid. Look at Reactive Groups 20 (organosulfides), 7 (amines), and 3 (carboxylic acids) may give indications about reactive tendencies. L-Methionine is an amino acid essential in human nutrition. |
Health Hazard | ACUTE/CHRONIC HAZARDS: L-Methionine is dangerous when heated to decomposition; it emits dangerous and highly toxic fumes. |
Fire Hazard | Flash point data for L-Methionine is not available, but L-Methionine is probably combustible. |
