β-Gentiobiose (CAS 554-91-6)

β-Gentiobiose is a disaccharide composed of two glucose molecules connected through a β-glycosidic bond. It is a naturally occurring carbohydrate found in various plant sources, including gentian plants (from which it derives its name), as well as fruits, vegetables, and grains. Scientifically, β-gentiobiose has been studied for its diverse applications and properties. It serves as a substrate for various enzymatic reactions, including those involving glycosidases and glycosyltransferases, making it valuable in enzymology research. It also acts as a precursor or substrate in the synthesis of complex carbohydrates and glycosides. In terms of its mechanism of action, β-gentiobiose functions as a source of glucose upon enzymatic hydrolysis by β-glucosidases. These enzymes break the β-glycosidic bond, releasing individual glucose molecules. The liberated glucose can then be utilized by the body as an energy source or participate in various metabolic pathways. Furthermore, β-gentiobiose exhibits prebiotic properties by selectively promoting the growth and activity of beneficial bacteria in the gastrointestinal tract. It can serve as a substrate for fermentation by gut microbiota, contributing to their overall health-promoting effects.
