Diastereomer of d-glucose
WebApr 6, 2024 · Enantiomers have every single stereocenter in opposite orientations, such as with D-glucose and L-glucose, while diastereomers have at least one stereocenter in the opposite orientation, but every stereocenter is not in the opposite orientation, such as with D-glucose and D-galactose. 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 and D-altrose diastereomers example. Both of these diastereomers examples belong to the carbohydrates group. In both of them, the chiral carbons are surrounded by the same type of substrates or molecules, but the difference lies in their positioning which in turn affects their configuration. WebReduction of d-fructose with sodium borohydride yields a mixture of two alditols. Explain why. Name the two alditols. Answer: Reduction of the carbonyl group gives a mixture of diastereomers that differ at C-2. One of these isomers has the same configuration as the alditol of glucose, glucitol.
WebThe d-family of aldohexoses comprising eight diastereomers can be obtained by stepping up d-aldopentoses.For example, d-glucose and d-mannose are obtained by stepping up d-arabinose as shown in Fig. 2.35 B.
