Functions and Effects

 

 

 

 

L-Asparagine serves as a building block for protein synthesis and supports normal cellular growth and metabolic balance. It functions as an important nitrogen carrier, helping transport ammonia between tissues and contributing to nitrogen homeostasis. In protein biochemistry, it provides the key site for N-linked glycosylation, influencing protein folding, stability, and biological activity. It can be converted to aspartate and participates in amino acid interconversion pathways. In cell culture applications, L-Asparagine supports cell viability, proliferation, and recombinant protein production. Its biochemical versatility makes it a reliable raw material for research, bioprocessing, and specialized formulation development.

FAQ

 

 

Q1:What is the difference between anhydrous and monohydrate L-Asparagine?
A1:The anhydrous form (CAS 70-47-3) contains no water of crystallization, while the monohydrate (CAS 5794-13-8) contains one molecule of water per molecule of asparagine. The monohydrate is more commonly supplied and exhibits approximately 12% water content by weight. Grade selection should be based on your formulation requirements, stoichiometric calculations, and storage conditions.
Q2:What is the optical purity and specific rotation?
A2:Our L-Asparagine is supplied as the L-enantiomer with optical purity ≥99%. The specific rotation [α]D²⁰ typically falls within +33.0° to +35.5° (c=2, in 6N HCl), consistent with USP/EP reference standards. Enantiomeric excess is confirmed by polarimetry and/or chiral HPLC.
Q3:How does L-Asparagine function in cell culture media?
A3:L-Asparagine is a non-essential amino acid that serves as a nitrogen donor and a building block for protein synthesis. It is a standard component of MEM, DMEM, RPMI-1640, and other mammalian cell culture formulations. It supports cell proliferation, recombinant protein expression, and metabolic homeostasis. Certain cell lines (e.g., some leukemia models) are auxotrophic for asparagine and require exogenous supplementation.
Q4:What are the recommended storage conditions and shelf life?
A4:Store in a tightly sealed container at 2–8°C or in a cool, dry place (≤25°C), protected from moisture and light. L-Asparagine is slightly hygroscopic and may degrade under prolonged exposure to heat or humidity. Typical shelf life is 24–36 months when stored properly; confirm the expiry date on the batch-specific COA.
Q5:Do you support custom packaging and bulk supply?
A5:Yes. We offer standard packaging (e.g., 1 kg, 5 kg, 25 kg) as well as customized OEM packaging and bulk quantities. Please specify your target grade, quantity, destination country, and intended application so we can provide an accurate quotation and relevant technical documentation.
