Note: Remember chiral carbon atoms are the carbon atoms which lack symmetry and have four different substituents attached to it. Chiral carbon is also known as asymmetric carbon. Enantiomers are pairs of compounds which are non …
WebNumber of chiral carbon in glucose. The structure of glucose is as follows:-. Because they all have four different substituents attached to them, the middle four carbon atoms in the chain are chiral. In the last carbon, two hydrogens are attached. So, this is not chiral. The number of chiral carbon in glucose is 4. Suggest Corrections. WebIn the case of glucose, a 6-membered ring is thermodynamically more stable than a 5-membered ring, thus favoring the formation of a 6-membered ring over a 5-membered ring. ... If you notice this cyclization process creates a new stereogenic center, C-1, which is referred to as the anomeric carbon. Glucose can exist as an α or a β isomer ...
