Question

In the detailed stereochemistry of carbohydrates, naturally occurring $\alpha$ -D-(+)-glucose and $\beta$ -D-(+)-glucose possess distinct spatial geometries solely at the hemiacetal carbon (C1). What highly specific term is utilized to classify this unique diastereomeric relationship?

Prashant Kotian · Accepted Answer

Correct answer: C. -D-glucose and -D-glucose are definitively diastereomers because they differ in stereochemistry, but not at all chiral centers. Because this structural inversion occurs exclusively at the highly specific C1 hemiacetal carbon (the anomeric carbon), they are officially sub-classified by IUPAC terminology as "Anomers".
