[PDF] [PDF] Experiment 11 – Carbohydrates

When Seliwanoff's reagent is reacted with a disaccharide or a polysaccharide, the acid in the solution will first hydrolyze them into monosaccharides, and the resulting monosaccharides can then be dehydrated Disaccharides and polysaccharides will therefore react slowly with Seliwanoff's reagent
