Ribose open chain
WebbGlucose Structure Open-Chain Formula The open-chain formula of glucose can be constructed with the following facts: Molecular Formula: From the analysis of elements of glucose and from the molecular weight of glucose the molecular formula that is C 6 H 12 O 6 is established. WebbSucrose is a disaccharide that is made up of a glucose and a fructose molecule, bound by a glycosidic linkage. A disaccahridase, called sucrase, breaks down sucrose molecules into their component monosaccharides (glucose and fructose), which can then by absorbed by the enterocytes in the small intestine.
