D-(+)-Cellobiose, identified by CAS number 528-50-7, is a disaccharide that plays a significant role in various scientific disciplines, particularly in glycoscience and biochemical research. As a readily available and well-characterized compound, it serves as a valuable tool for scientists and researchers worldwide. For those looking to buy D-cellobiose for these applications, understanding its utility is key.

The Significance of D-Cellobiose in Glycoscience
Glycoscience is the study of the structure, biosynthesis, and biological function of saccharides (sugars). D-(+)-Cellobiose, being a dimer of glucose with a specific β-(1→4) linkage, is a fundamental building block for understanding more complex carbohydrates, including cellulose, the most abundant biopolymer on Earth. Researchers often use D-cellobiose to study enzymatic pathways involved in carbohydrate metabolism, enzyme kinetics, and the interactions of carbohydrates with proteins and other biomolecules. Its predictable structure makes it an excellent model compound for investigating glycosidic bond hydrolysis and synthesis.

D-Cellobiose as a Biochemical Tool
In microbiology and biochemistry, D-(+)-Cellobiose serves multiple purposes:

• Carbohydrate Source in Culture Media: It is frequently added to culture media as a nutrient supplement, providing a readily usable source of energy and carbon for microorganisms. This is particularly useful when studying specific metabolic pathways or the growth requirements of certain bacteria.
• Bacterial Differentiation: Many bacteria possess enzymes capable of fermenting cellobiose, while others do not. This differential fermentation ability can be used to identify and classify bacterial species. For instance, the production of acid from cellobiose fermentation, detectable with pH indicators, is a diagnostic characteristic for some genera.
• Enzyme Assays: D-cellobiose is an important substrate for studying the activity of various enzymes, such as cellulases and β-glucosidases. These enzymes are critical in many biological processes and industrial applications, and using purified D-cellobiose as a substrate allows for precise measurement of enzyme activity.

Where to Buy D-Cellobiose
For researchers and laboratories, sourcing high-purity D-(+)-Cellobiose (CAS 528-50-7) is essential. When you need to buy D-cellobiose, look for suppliers that provide detailed product specifications, including purity levels (typically >98% by HPLC) and reliable analytical data. Many chemical suppliers offer D-cellobiose in various packaging sizes, from laboratory quantities to bulk amounts for larger research projects or pilot studies. Consider established chemical manufacturers and distributors, especially those specializing in carbohydrates or fine chemicals.
