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 ... WebWhen d-glucose crystallizes from methanol, α-d-glucose, which melts at 146 °C, forms. It has [α] d = + 112.2°. On the other hand, when α-d-glucose crystallizes from acetic acid, the β anomer, which melts at 150 °C, forms. It has [α] d = + 18.7° (Figure 28.6). The α and β isomers are diastereomers, so it is not surprising that they ...

"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… " - Diastereomer of d-glucose
