Boat conformation of glucose
WebChair and Boat Conformation of Glucose: The glucopyranose and fructofuranose rings (α or β) of glucose can assume several non-planar shapes, one of them being the “chair” conformation. Glucopyranose may assume chair or boat conformation whereas fructofuranose may assume envelope conformation. WebMar 28, 2013 · Correspondingly, in the crystal of 2, the non-aromatic six-membered ring showing a distorted boat conformation is anti-fused along the C8–C2′ bond to a five-membered ring, placing the atoms O4 and C8 on the prow and stern positions deviating by 0.376(3) and 0.778(3) Å, respectively, from the mean plane of the other four atoms .

WebJan 13, 2024 · The most important thing to draw the correct conformation of a sugar, D-glucose, is to pay attention to the stereochemistry from C-2 to C-5, because any change in the configuration of these stereogenic centers changes the identity of the sugar D-glucose. At first we need to change the hydroxyl group on C-5 in the proper orientation.
