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. The staggered zigzag formulas of d-glucose and d-mannose are drawn in a similar manner as described for d-aldopentoses with R … WebThe other six diastereomers of the d-aldohexose family can also be obtained by the stepping up procedure: d-ribose gives d-allose and d-altrose, ... Using d-glucose as precursor requires substitution of the C-2 or C-5 position with retention of configuration, by double inversion. WebAnd if these diastereomers are cyclic hemiacetals like sugars are, then they are classified as anomers. Therefore, D and L Glucose are enantiomers, while ɑ-D-glucose and β-D-glucose are diastereomers. To summarize what we learned about epimers and anomers. Epimers are diastereomers that differ in the configuration of only one chiral center. irtra historia
