At equilibrium in solution,D-glucose consists of a mixture of its anomers.Which statement most accurately describes this solution?
A)The solution consists of approximately equal amounts of the $\alpha$- and $\beta$-anomers.
B)The straight-chain form is present in high concentration.
C)The $\alpha$-anomer is more stable and is slightly preferred over the $\beta$-anomer.
D)The $\beta$-anomer predominates over the $\alpha$-anomer by a ratio of approximately 2:1.
E)None of the answers above is correct.

Question

Quizplus · Accepted Answer

The β-anomer of D-glucose is more stable due to the equatorial position of the hydroxyl group at the anomeric carbon, leading to its predominance in solution by approximately a 2:1 ratio over the α-anomer.
