(UDP-GlcNAc - an essential sugar nucleotide that drives protein function and cellular communication

5′-uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) is one of the most critical sugar nucleotides in cells and is known as the “universal currency of glycosylation reactions”. It is not only the core substrate for the synthesis of sugar chains in organisms, but also an indispensable high-value raw material in the fields of glycobiology research, protein drug optimization and metabolic disease research.

Chemical Information

· Chemical name: 5′-uridine diphosphate-N-acetylglucosamine disodium salt

· English name: UDP-ALPHA-D-N-ACETYLGLUCOSAMINE,DISODIUM SALT

· Chemical formula: C17H28N3NaO17P2

· Molecular weight: 631.35g/mol

· CAS number: 91183-98-1

Structural features

The structure of UDP-GlcNAc combines high-energy bonds and specificity:

· High-energy diphosphate bond bridge: Uridine and N-acetylglucosamine in the molecule are connected through a high-energy diphosphate bond (UDP). This structure serves as an energy carrier and activating group in enzymatic reactions, providing driving force for the glycosylation process.

· Precise three-dimensional configuration: Its α-D-configuration ensures that it can be accurately recognized by specific glycosyltransferases, thereby transferring N-acetylglucosamine units to specific sites on proteins, lipids or other sugar chains in a highly specific manner.

Main applications and advantages

1. Key reagents for protein glycosylation research and biopharmaceuticals

· N-linked and O-linked glycosylation: UDP-GlcNAc is an exclusive substrate for glycosyltransferases in the cellular endoplasmic reticulum and Golgi apparatus, responsible for initiating and elongating N-linked and O-linked sugar chains of proteins. Our high-purity products are core tools for studying protein glycosylation mechanisms and elucidating glycoprotein structures.

· Optimizing therapeutic protein drugs: The glycosylation pattern of a protein directly affects its stability, half-life and biological activity. In the biopharmaceutical process, by regulating the glycosylation process (using UDP-GlcNAc and other substrates), the efficacy and druggability of protein drugs such as monoclonal antibodies and enzyme replacement therapy can be significantly improved.

2. Core molecules in cell signaling and metabolic regulation

· O-GlcNAc glycosylation modification: UDP-GlcNAc is the only substrate for dynamic O-GlcNAc modification. This modification occurs on serine/threonine residues and competes with phosphorylation. As an important nutrient and stress sensor, it is widely involved in key life processes such as transcriptional regulation, cell cycle, and signal transduction. Our products are ideal probes for exploring the mechanisms of diseases related to metabolic abnormalities such as diabetes, cancer, and neurodegenerative diseases.

3. The cornerstone of sugar chain synthesis and cell wall research

· Glycosaminoglycan and glycolipid synthesis: As the starting unit of sugar chain extension, UDP-GlcNAc is an essential precursor for the biosynthesis of glycosaminoglycans such as hyaluronic acid and heparin, as well as complex glycolipids.

· Microbial research: In bacteria and fungi, UDP-GlcNAc is the core building block for peptidoglycan and chitin cell wall synthesis, making it an important target for the development of new antibacterial drugs.

Conclusion

5′-uridine diphosphate-N-acetylglucosamine disodium salt is much more than a biochemical reagent. It is the molecular engine that decodes the sugar code of life and empowers the next generation of biopharmaceuticals. From precisely regulating protein functions to uncovering disease signaling pathways, from optimizing biopharmaceutical processes to developing new antibacterial strategies, its application prospects are extremely broad.
