Cellulose cannot be hydrolysed in human body because of the absence of that particular enzyme in the body, hence it cannot be digested in human body.

D-Glucose forms silver mirror with Tollen's reagent and give a red ppt with Fehlings solution. This show that D-glucose is a reducing sugar.

When an optically active compound show change in specific rotation with time up to an equilibrium value the phenomena is mutarotation.

The source of pectin is fruit skin. They are used in drug preparation, where they are used as inert agents to suspend as active drug.

Carbohydrates which reduce Tollen's reagent and give red ppt with Fehling's solution are called reducing sugars. All monosaccharides (both aldoses and ketoses) and disaccharides except sucrose are reducing sugars.
