DescriptionECHEMI Editorial ReferenceL-Asparagine is a non-essential amino acid that is involved in the metabolic control of cell functions in nerve and brain tissue.
DryPowder|Solid
L-asparagine is an optically active form of asparagine having L-configuration. It has a role as a nutraceutical, a micronutrient, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a plant metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, an asparagine and a L-alpha-amino acid. It is a conjugate base of a L-asparaginium. It is a conjugate acid of a L-asparaginate. It is an enantiomer of a D-asparagine. It is a tautomer of a L-asparagine zwitterion.|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. (From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed)|Asparagine is a non-essential amino acid in humans, Asparagine is a beta-amido derivative of aspartic acid and plays an important role in the biosynthesis of glycoproteins and other proteins. A metabolic precursor to aspartate, Asparagine is a nontoxic carrier of residual ammonia to be eliminated from the body. Asparagine acts as diuretic. (NCI04)|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.
