Question

α - D - glucose and β - D - glucose differ from each other due to the difference in one of the carbons with respect to its ________.

• A. Size of hemiacetal ring
• B. Configuration
• C. Number of OH groups
• D. Conformation

Answer 1

The correct option is B Configuration

Anomers are diastereoisomers of cyclic forms of sugars or similar molecules differing in the configuration at the anomeric carbon (C-1 atom of an aldose or the C-2 atom of a 2-ketose). The cyclic forms of carbohydrates can exist in two forms, α- and β- based on the position of the substituent at the anomeric center.
