Identify the difference between α and β anomers of D-glucopyranose:  
ADifferent molecules
BDiffer in configuration at C1 (anomeric center) only
CSame molecule, identical
DDiffer at C5
Answer & Solution
Correct answer: B. Differ in configuration at C1 (anomeric center) only
α and β anomers differ ONLY at C1 (anomeric carbon). In α: C1 -OH below ring (trans to CH₂OH). In β: above ring (cis to CH₂OH). All other stereocenters identical. β is slightly more stable (equatorial -OH at C1).
