What Is L-Methionine?
L-Methionine is a sulfur-containing amino acid identified by CAS 63-68-3. The supplied white crystalline ingredient has a specified assay of 98.5–101.5%.
Its L-form identity distinguishes it from DL-methionine and from methionine-containing protein hydrolysates. It can be evaluated in amino acid blends and professional nutrition ingredient systems that require a defined methionine contribution. Formulation calculations should use the stated assay and identity rather than treating different stereochemical forms or protein-bound sources as interchangeable raw materials.
