Difference Between Cellobiose and Cellulose

Thekey differencebetween cellobiose and cellulose is thatcellobiose is adisaccharide, whereas cellulose is apolysaccharide.

纤维素和纤维素是碳水化合物化合物。我们可以分类carbohydratesinto different categories such as monosaccharides, disaccharide and polysaccharides, depending on the structure and the complexity of the carbohydrate. A monosaccharide is a simple sugar, while a disaccharide is a combination of two monosaccharides and a polysaccharide is a combination of many monosaccharide units.

What is Cellobiose?

Cellobiose is a carbohydrate with the chemical formula C₁₂H₂₂O₁₁. We can categorize it as a disaccharide. It is a reducing sugar. That means; the cellobiose can act as a reducing agent because it has a free ketone group in its structure. Cellobiose has two beta-glucose molecules linked via beta 1-4 glycosidic linkage. However, it is different from maltose because the configuration at the glycosidic bond is different. We can hydrolyze this compound into glucose by enzymatic means or by chemical means using an acid.

When considering the structure of cellobiose, there are eight free alcohol groups along with an acetal group and a hemiacetal group. These groups provide the molecule with an ability to form strong intermolecular hydrogen bonds.

我们可以从含纤维素或纤维素的材料（例如纸，棉花等）中获取纤维二糖。在这里，我们需要这些材料的酶促水解或酸性水解，以从这些材料中获取近生二糖。该化合物对于检测克罗恩病作为碳水化合物的指标也很重要。

What is Cellulose?

Cellulose is a carbohydrate we can categorize as a polysaccharide and it has the chemical formula (C₆H₁₀O₅)n. It may contain hundreds to thousands of D-glucose units, linked to each other via beta 1-4 glycosidic bonds. If we produce or isolate it from a source, it appears as a white powder. Cellulose is present as an important structural unit of cell walls in plants and algae. Sometimes, some bacteria species also secrete cellulose to form biofilms. Therefore, we can say that cellulose is the most abundant polymer material on Earth.

纤维素是一种无味的无色化合物。它不溶于水和许多有机溶剂。此外，它是一种手性化合物，也是可生物降解的。我们可以通过在较高温度下添加高浓缩的无酸，将纤维素分解为葡萄糖单元。与淀粉相比，该化合物是高度结晶的，并且在加热时也可以从结晶到无定形结构。

When considering the applications of cellulose, it is mainly used in the production of paper and paperboard. We can also use it for the production of cellophane and rayon. In addition to these, there are research studies exploring the conversion of cellulose into biofuel.
