In stereochemistry, diastereomers (sometimes called diastereoisomers) are a type of stereoisomer. Diastereomers are defined as non-mirror image, non-identical stereoisomers. Hence, they occur when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other. Wh… Webd-Glucose is an aldohexose type sugar, occurring generally in six-membered ring form (α- and β-glucopyranose, see Carbohydrates Figure 3).Together with its β1-4-gucoside polymer, cellulose, d-glucose is the most abundant organic matter in the terrestrial biosp here (Kamide, 2005).
