When $\alpha$-D-glucopyranose is dissolved in water, mutarotation occurs. What has happened?

Question

Quizplus · Accepted Answer

Mutarotation is the phenomenon where a carbohydrate in water converts to a mixture of α- and β- anomers (in the case of glucose, these are α-D-glucose and β-D-glucose). Therefore, option B is correct as the carbohydrate has converted to a mixture of α- and β-anomers. Option A is incorrect as the conversion is not complete to one specific anomer. Option C is incorrect as mutarotation does not involve the conversion to the enantiomer. Option D is incorrect as mutarotation does not involve a change in configuration from D- to L-.
