QUALITATIVE EXPERIMENT [REDUCING SUGARS] AIM: To determine which of the three sugars tested (Glucose, Fructose and Sucrose) is a reducing sugar by heating them with Benedict's solution. BACKGROUND INFORMATION: A carbohydrate is an organic compound that is composed of atoms of Carbon, Hydrogen and Oxygen in the ratio 1:2:1. Carbohydrates used in the experiment can be divided into two groups:> Monosaccharides: All monosaccharides have the general formula (CH2O) n; where 'n' can be any number between 3 and 9. All monosaccharides also contain a carbonyl (C=O) group and at least two hydroxyl (OH) groups. The monosaccharides used in this experiment are called Hexose, which have six carbon sugars. All the hexoses have the general formula C6H12O6. They can exist as straight chains or rings. Two common hexoses are glucose and fructose (see figure below). Hexoses are sources of energy in respiration and are the monomers, which link together to form disaccharides and...
