L-Methionine
Chemical and Physical Properties of L-Methionine L-Methionine has the molecular formula C₅H₁₁NO₂S and a molecular weight of 149.21. Its chemical structure features a methylthio group (-S-CH₃) attached to the side chain, which is the core functional group responsible for its biological activities. It exists as a white crystalline powder with a slight characteristic odor, high solubility in water (approximately 33 g/L at 25℃), and solubility in dilute acids and alkalis, but low solubility in organic solvents such as ethanol and ether. It is optically active, with a specific rotation of +21° to +25° (c=1, water), and is stable under normal storage conditions, though it may decompose when exposed to high temperatures or strong oxidizing agents.
