Are D-glucose And L-glucose Diastereomers? - On Secret Hunt

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. WebWouldn't all but one of the L-stereomers also be diastereomers to all but one of the D-stereomers as well? For example, L-Glucose is an enantiomer to D-glucose but all other L-aldohexoses should be a diastereomer to D-glucose, correct? Also, if epimers differ at only one stereocenter, shouldn't there exist an L-aldohexose (2R,3S,4R,5S) that is ... port townsend web cameras ferry
