DL-Methionine
DL-Methionine, chemically designated asDL-2-amino-4-(methylthio)butanoic acid, is a racemic mixture consisting of equimolar quantities of L-methionine and D-methionine, with a molecular formula ofC5H11NO2Sand a relative molecular mass of 149.21 g/mol. As a sulfur-containing amino acid, its chemical properties are governed by the combined effects of its functional groups—including the amino group (-NH2), carboxyl group (-COOH), and methylthio side chain (-CH2CH2SCH3)—as well as its racemic composition. These properties underpin its reactivity in acid-base reactions, redox reactions, substitution reactions, and complexation reactions, which are closely linked to its applications in feed, food, and pharmaceutical industries.
