Genel Bakış

L-Glutamine is an amino acid whose amide side chain gives it a chemical profile distinct from those of branched-chain amino acids and basic amino acids such as arginine. Its assay is controlled at 98.5–101.5%, and its identity is confirmed by infrared spectroscopy against a reference standard, defining the material for nutrition formulators.

The specified optical rotation range, +6.3° to +7.3°, provides a stereochemical check on quality. It helps verify that the material is the L-form required by the product specification instead of relying solely on total nitrogen or a generic amino-acid assay.

With loss on drying at no more than 0.3% and residue on ignition at no more than 0.1%, this crystalline grade suits dry formulations that require tight control of moisture and inorganic residue. Organic volatile matter must meet the relevant requirements as well, making the grade suitable for producing powders, capsules, and tablets.
