Kindly separate the examples of all the types of saccharides into reducing and nan-reducing. (Eg: Glucose, sucrose, maltose..etc. etc.) Plus, lemme know if there's any way to find out whether it's reducing or not.

Sucrose is non-reducing and maltose and glucose both are reducing. The way determine is that when react these monosaccharides with fehling's or Tollen's reagent it changes it colour by oxidising cupric ions to copper oxide. All monosaccharides are reducing in nature.
