Sucrose is a non-reducing sugar because it is a disaccharide composed of glucose and fructose linked by their anomeric carbons in a glycosidic bond, which cannot undergo mutarotation to an open-chain form. Xylulose, glucose, and maltose are all reducing sugars because they have a free anomeric carbon that can open to form an aldehyde or ketone group and reduce other compounds, such as copper ions.
