Glucose, Fructose, Maltose
Reducing sugars contain free anomeric carbon that can reduce Benedict's or Fehling's reagent. Glucose, fructose, and maltose are reducing sugars, while sucrose is non-reducing as both anomeric carbons are involved in glycosidic linkage.

Show answer
Adenine, Guanine
Purine bases have double ring structure. Adenine and Guanine are purines. Cytosine, Thymine, and Uracil are pyrimidines with single ring structure.
