sugars - 2023 ILLIAC (Cornell)

Benedict’s reagent helps identify examples of these compounds that are reducing. For 10 points each:

[10e] Name these sweet-tasting carbohydrates that include glucose and sucrose.

ANSWER: sugars

[10h] Reducing sugars undergo this process when changing between anomers, which results in a change in optical rotation.

ANSWER: mutarotation

[10m] Anomers that mutarotate have this relationship with each other in which they are non-mirror image stereoisomers of each other.

ANSWER: diastereomers
