D-(+)-Cellotriose is primarily used in biochemical research to study cellulose degradation and enzymatic processes. It serves as a substrate for cellulase enzymes, helping to understand their mechanism and efficiency in breaking down cellulose into simpler sugars. This compound is also utilized in the development of biofuel production methods, as it aids in optimizing the conversion of cellulose into fermentable sugars. Additionally, D-(+)-Cellotriose is employed in the food industry to investigate its potential as a prebiotic, promoting the growth of beneficial gut bacteria. Its role in material science includes the study of cellulose-based materials and their structural properties. It can also serve as an intermediate in the synthesis of other carbohydrate compounds.
