Question

Quizplus · Accepted Answer

Anomeric pair refers to the pair of stereoisomers resulting from the hemiacetal or hemiketal formation between a carbonyl group (e.g. aldehyde or ketone) and an alcohol group in the same molecule. Option D presents two forms of glucose, one in α-anomeric form and one in β-anomeric form, making them an anomeric pair. Options A, B, and C do not present an anomeric pair as they do not have two forms resulting from hemiacetal or hemiketal formation. Option E presents glucose and fructose in different anomeric forms, but they are not the same type of sugar and thus not an anomeric pair.
