Additional Infomation	Asparagine is an alpha-amino acid in which one of the hydrogens attached to the alpha-carbon of glycine is substituted by a 2-amino-2-oxoethyl group. It has a role as a Daphnia magna metabolite and an algal metabolite. It is an alpha-amino acid, a dicarboxylic acid monoamide and a polar amino acid. It contains a 2-amino-2-oxoethyl group. It is a conjugate base of an asparaginium. It is a conjugate acid of an asparaginate. DL-Asparagine has been reported in Drosophila melanogaster, Trifolium repens, and other organisms with data available. A non-essential amino acid that is involved in the metabolic control of cell functions in nerve and brain tissue. It is biosynthesized from ASPARTIC ACID and AMMONIA by asparagine synthetase.

*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.
