|Description||L-Glutamine (Gln) is one of the 20 amino acids encoded by the standard genetic code and also a major respiratory fuel and substrate for nucleic acid synthesis in mammalian intestinal cells.|
L-Glutamine (0.2 and 2 mM) but not D-Gln inhibits the generation of L-Arg by both Arg-depleted and nondepleted endothelial cells. L-Glutamine also inhibits the conversion of L-[14C]Cit to L-[14C]Arg by Arg-depleted endothelial cells. L-Glutamine interferes with the conversion of L-Cit to L-Arg probably by acting on argininosuccinate synthetase rather than argininosuccinate lyase. L-Glutamine also inhibits the generation of L-Arg by the monocyte-macrophage cell line J774 but has no effect on the conversion of L-Cit to L-Arg by these cells.  L-Glutamine metabolism stimulates Na+-H+exchange of acid-loaded porcine enterocytes by a mechanism not requiring activation of PKC.  L-Glutamine (0.2 mM and 2 mM) but not D-glutamine (2 mM), L-glutamic acid (2 mM) or ammonium chloride (1 mM) also inhibits the generation of L-arginine in endothelial cells.  L-glutamine promotes chromatin condensation and formation of crescent-like structures in the nucleus of murine primary microglia as well as of the microglial cell-line BV-2. 
|In vivo||L-Glutamine at 0.5, 2 and 5 mM dose-dependently reduces H(2)O(2)- or LPS-induced cell death by 14%, 54% and 95%. L-Glutamine increases Glutamine concentrations in small-intestinal lumen and plasma, reduces intestinal expression of Toll-like receptor-4, active caspase-3 and NFkB, ameliorates intestinal injury, decreases rectal temperature, and enhanced growth performance in LPS-challenged piglets. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
