http://www.chem.uiuc.edu/organic/Carbohydrates/Chapter%209/sec9-4/9-4.htm WebTo be considered chiral, the carbon has to have 4 different substituents. You do NOT only look at the single atom that is connected to the carbon. So for B-d-glucapyranose, the O (-R) and OH are two different substituents with the 3rd being the Hydrogen, and the 4th being the rest of the molecule starting with C2.

One of … WebAnd similarly with glucose, one, two, three, four, five, six. So the only carbon that these differ at is the C4, and because they just differ at one carbon we have a special word for these, and they're called epimers. Epimers are diastereomers that differ at one chiral center.

WebA chiral centre is an atom that has four different groups bonded to it. Therefore, glucose has 4 centers: First atom has a double bond with oxygen which automatically means it can not have 4 different groups (carbon forms 4 bonds) and the sixth one has 2 hydrogen atoms which means that this atom has 3 different groups bonded to it.
