Question

$\alpha$-D(+)- and $\beta$-D(+)-glucopyranoses are known as:

• A. epimers
• B. Anomers
• C. Tautomers
• D. Enantiomers

Answer 1

Answer: (B)

Anomers

α - D (+) - and β - D (+) - glucopyranoses are known as anomers.
Anomers are cyclic monosaccharides or glycosides that are epimers, differing from each other in the configuration of C-1 if they are aldoses or in the configuration at C-2 if they are ketoses. The epimeric carbon in anomers are known as anomeric carbon or anomeric center.
