D-(+)-Cellobiose 528-50-7 CAS NO.528-50-7

Description of D-(+)-Cellobiose from Wuhan Fortuna Chemical Co.,Ltd

What is D-(+)-Cellobiose

D-(+)-Cellobiose is a disaccharide composed of two glucose molecules linked by a β(1→4) glycosidic bond. It is a structural subunit of cellulose, which is a major component of plant cell walls. In simpler terms, cellobiose is a sugar formed from the breakdown of cellulose, which is an abundant natural polymer found in plants.

Application of D-(+)-Cellobiose

D-(+)-Cellobiose has various applications in research, industry, biotechnology, and diagnostics due to its role as a disaccharide derived from the breakdown of cellulose. Here are its main applications:

1. Carbohydrate Research and Cellulose Study - Model Compound for Cellulose: Since cellulose is composed of repeating D-(+)-cellobiose units, this disaccharide serves as a useful model compound for studying cellulose structure, properties, and degradation. It helps researchers understand the interaction between cellulose and enzymes, and how cellulose can be broken down into simple sugars.

- Enzymatic Studies: Cellobiose is critical for studying the activity of cellulases and β-glucosidase, enzymes that break down cellulose and hemicellulose into glucose. This is especially important for understanding how cellulose is degraded in nature and how to replicate that process in industrial applications like biofuels.

2. Biofuel Production and Biotechnology - Biomass Conversion to Sugars: In the production of biofuels from plant biomass, D-(+)-cellobiose is a key intermediate in the enzymatic hydrolysis of cellulose. In this process, cellulases break cellulose down into cellobiose, which is further hydrolyzed into glucose. Understanding and improving this process can help in producing ethanol and other biofuels from renewable sources like wood, grasses, and agricultural waste.

- Improving Enzyme Efficiency: Researchers use cellobiose to optimize the action of enzymes involved in biomass conversion. Efficient breakdown of cellobiose into glucose is vital for maximizing the yield of fermentable sugars from biomass.  

3. Synthetic Chemistry - Synthesis of Oligosaccharides: D-(+)-cellobiose is used in the synthesis of more complex carbohydrates and oligosaccharides. Its well-defined structure makes it a valuable intermediate for creating larger sugar molecules that are useful in materials science, pharmaceuticals, and biotechnology.

- Cellulose Derivatives: Cellobiose can serve as a precursor in the chemical synthesis of cellulose derivatives like carboxymethyl cellulose (CMC) or cellulose acetate, which are used in making films, plastics, and fibers.

4. Food and Nutrition - Prebiotic Potential: While not widely used as a food ingredient, D-(+)-cellobiose is being researched for its potential as a prebiotic, which could promote the growth of beneficial gut bacteria. More studies are needed to understand how cellobiose could contribute to gut health. - Natural Sweetener: Although mildly sweet, cellobiose is not commonly used as a sweetener. However, its low sweetness and role as a carbohydrate might make it a candidate for future food applications.  

5. Medical and Diagnostic Applications - Assessment of Intestinal Permeability (Lactulose/Mannitol Test): Cellobiose can be used in diagnostic tests to evaluate the permeability of the small intestine. The test involves administering cellobiose orally and measuring its excretion in urine. If excessive amounts of cellobiose are found in the urine, it may indicate increased intestinal permeability, sometimes referred to as "leaky gut syndrome." - Potential Therapeutic Use: Research into how certain carbohydrates like cellobiose affect gut health and metabolism could lead to its use in therapeutic applications, especially in gastrointestinal health or metabolic conditions.

6. Environmental and Agricultural Use - Biodegradation of Plant Waste: D-(+)-cellobiose is important in studying the decomposition of plant materials, especially in processes that involve composting or the microbial degradation of agricultural waste. Understanding how cellobiose is broken down helps in optimizing these processes for waste management and soil health. - Animal Feed Digestion Studies:** In ruminant animals (such as cows and sheep), cellobiose is an intermediate product of cellulose digestion by microbes in the gut. Research on cellobiose metabolism is important for improving animal feed efficiency and understanding the nutritional needs of livestock.

7. Paper and Textile Industries - Cellulase Enzyme Research: In industries like paper manufacturing and textile processing, D-(+)-cellobiose is used to study how cellulase enzymes can be applied to break down cellulose fibers. This is important in processes such as biobleaching, where enzymes are used to treat cellulose in environmentally friendly ways, or in the production of bio-based materials from plant fibers.

Summary of Key Applications:

- Research tool in carbohydrate chemistry and cellulose degradation studies. -Biofuel production by converting plant biomass into glucose for fermentation. - Enzymatic research for cellulase and β-glucosidase efficiency optimization. - Precursor for synthesizing oligosaccharides and cellulose derivatives in synthetic chemistry.

- Diagnostic tool for assessing intestinal permeability.

- Environmental and agricultural researchin biodegradation and animal feed digestion studies.

-Industrial use in paper, textile, and other cellulose-processing industries. In summary, D-(+)-cellobiose plays a vital role in understanding cellulose degradation, improving biofuel production, advancing enzymatic research, and has potential applications in nutrition and diagnostic medicine. Its importance lies in its structure as a disaccharide derived from cellulose, making it a valuable intermediate in both natural processes and industrial applications.
