Biological Activity

Targets	Endogenous Metabolite; Microbial Metabolite
ln Vitro	Glutamine is an alpha-amino acid that consists of butyric acid bearing an amino substituent at position 2 and a carbamoyl substituent at position 4. It has a role as a fundamental metabolite. It is an alpha-amino acid and a polar amino acid. It contains a 3-amino-3-oxopropyl group. It is a conjugate base of a glutaminium. It is a conjugate acid of a glutaminate.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
