L-Glutamine is a conditionally essential amino acid and the most abundant free amino acid in human plasma and skeletal muscle. It is manufactured via microbial fermentation and supplied as a white crystalline powder that meets USP/EP/AJI standards, with an assay of 99.0%–101.0% on a dried basis.
As a key nitrogen transporter and precursor for nucleotides, glutathione, and proteins, L-Glutamine is widely used in clinical nutrition, sports supplements, and biopharmaceutical cell culture media. Its role in intestinal health and immune function makes it a staple in enteral and parenteral formulations.
