Final Answer:The anomeric carbon atoms of sucrose are C1 of glucose and C2 of fructose. Sucrose is nonreducing.Explanation:Sucrose, a disaccharide composed of glucose and fructose, lacks a free anomeric carbon due to the glycosidic bond formed between the two monosaccharides. The glycosidic bond links the anomeric carbon of glucose (C1) to the hydroxyl group of fructose's anomeric carbon (C2).This bond structure prevents sucrose from undergoing mutarotation, a process where the α and β anomers interconvert, which typically characterizes reducing sugars. Since sucrose's anomeric carbons are engaged in this linkage, they are unable to form open-chain structures and participate in reducing reactions, hence the term "nonreducing."Consequently, sucrose cannot reduce other compounds, such as Benedict's or Fehling's solution, which are commonly used in tests for reducing sugars. Its nonreducing nature makes sucrose suitable for applications where stability against oxidation is desired, such as in food preservation or as a sweetening agent in baked goods.Understanding the chemical properties of carbohydrates, including the role of anomeric carbons in determining reducing or nonreducing characteristics, sheds light on their diverse functionalities in biological systems and industrial applications....
