2-O-α-D-Mannopyranosyl-D-mannopyranose, with the CAS number 15548-39-7, is a disaccharide composed of two D-mannopyranose units linked by an α-glycosidic bond at the 2-position. This compound exhibits characteristics typical of carbohydrates, including solubility in water due to its hydroxyl groups, which can form hydrogen bonds with water molecules. It is a white, crystalline solid at room temperature and is generally stable under normal conditions. The presence of multiple hydroxyl groups contributes to its sweet taste and potential as a sugar substitute. In biological systems, it may play a role in various metabolic pathways and can be involved in cell recognition processes. Its structural features allow it to participate in glycosylation reactions, making it relevant in the study of glycoproteins and polysaccharides. Additionally, its properties can be influenced by factors such as pH and temperature, which may affect its stability and reactivity in different environments.
