D-Selobioz is an organic compound with the chemical formula C12H22O11, CAS 528-50-7, and a white crystalline powder. The molecule has a semi acetal hydroxyl group that can reduce Fehling reagent. It is the product of cellulose hydrolysis and the basic structural unit of cellulose. It cannot be hydrolyzed by maltase, but can be hydrolyzed by bitter almond enzyme and is a reducing sugar. There is no free fiber disaccharides in nature. Fine crystalline fiber disaccharides (after vacuum drying) can be obtained in ethanol aqueous solution. Its relationship with cellulose is similar to that of maltose and starch, and after hydrolysis, two molecules of D - (+) - glucose are also obtained. The difference is that maltose is - Glucosides, while disaccharides are - Glucosides. This substance belongs to dietary fiber and cannot be hydrolyzed by human digestive enzymes. It has physiological functions such as regulating blood sugar, peristalsis of the intestine, and lowering cholesterol. Fibrobiose can be used as an excipient for antibiotics, improving their solubility and bioavailability, as well as improving the texture and stability of other drugs. Fiber disaccharides are mainly used in the production of sugar free chewing gum and low sugar beverages, with a sweet taste but almost no calories, making them an ideal sugar substitute. Fibrobiose is a substrate for multiple enzyme and bacterial reactions, used to study the enzymatic mechanisms and sugar metabolism pathways of related enzyme systems, and can also be used as a raw material for fermentation to produce organic compounds. It is a raw material for synthesizing high vodka syrup, other oligosaccharides, and uronic acids. It plays an important role in biochemistry and is also an important precursor for the production of mucopolysaccharides, vitamin C, and dyes. Fibrobiose can be used as a thickener and moisturizer in the cosmetics, pharmaceutical, and food industries. It also has a certain chemical solvent effect.
