    Metabolic Functions & Application Versatility

    Regarding metabolic and physiological roles, L-Glutamine functions as a primary fuel source for enterocytes and immune cells. Sports nutrition formulators select L-Glutamine to accelerate muscle recovery, reduce exercise-induced soreness, and prevent glycogen depletion. Clinical nutrition producers incorporate pharma-grade L-Glutamine into parenteral and enteral formulations to preserve gut mucosal integrity and support post-surgical recovery. Because L-Glutamine maintains intestinal barrier integrity and nitrogen balance, L-Glutamine remains an essential amino acid globally.


    Commercial Advantage & Quality Assurance

    Partnering with an established L-Glutamine manufacture guarantees supply chain security and compliance with global pharmacopeial standards. SuperPharmaGroup provides a complete regulatory document package for every CAS 56-85-9 shipment:

    • Certificate of Analysis (COA) & Safety Data Sheet (SDS)

    • GMP, ISO 22000 & HACCP Quality Certificates

    • Halal & Kosher Food Safety Declarations

    • Non-GMO, BSE/TSE-Free & Heavy Metal Testing Reports

    ECHEMI Editorial Reference
    L-Glutamine is a non-essential amino acid present abundantly throughout the body and is involved in gastrointestinal disorders.Target: mGluRGlutamine (abbreviated as Gln or Q) is one of the 20 amino acids encoded by the standard genetic code. It is not recognized as an essential amino acid, but may become conditionally essential in certain situations, including intensive athletic training or certain gastrointestinal disorders. Its side-chain is an amide formed by replacing the side-chain

    L-glutamine is an optically active form of glutamine having L-configuration. It has a role as an EC 1.14.13.39 (nitric oxide synthase) inhibitor, a nutraceutical, a micronutrient, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a glutamine family amino acid, a proteinogenic amino acid, a glutamine and a L-alpha-amino acid. It is a conjugate base of a L-glutaminium. It is a conjugate acid of a L-glutaminate. It is an enantiomer of a D-glutamine. It is a tautomer of a L-glutamine zwitterion.|A non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from glutamic acid and ammonia. It is the principal carrier of nitrogen in the body and is an important energy source for many cells. An oral formulation of L-glutamine was approved by the FDA in July 2017 for use in sickle cell disease. This oral formulation is marketed under the tradename Endari by Emmaus Medical.|Glutamine is an Amino Acid.|L-glutamine is an essential amino acid and precursor of major intracellular antioxidant molecules that is used in high doses to prevent vaso-occlusive crises in patients with sickle cell disease. L-glutamine has not been associated with serum enzyme elevations during therapy or to instances of idiosyncratic acute liver injury.|Glutamine is a nonessential amino acid. Glutamine can donate the ammonia on its side chain to the formation of urea (for eventual excretion by the kidneys) and to purines (necessary for the synthesis of nucleic acids). Glutamic acid-to-glutamine conversion, in which an ammonia group is added to glutamic acid (catalyzed by glutamine synthase), is of central importance in the regulation of toxic levels of ammonia in the body. This agent is a substrate for the production of both excitatory and inhibitory neurotransmitters (glutamate and GABA) and is also an important source of energy for the nervous system. Glutamine may become a conditionally essential amino acid during certain catabolic states.|A non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from GLUTAMIC ACID and AMMONIA. It is the principal carrier of NITROGEN in the body and is an important energy source for many cells.
