The word “saccharide” means sugar, while the prefixes “mono”, “di” and “poly” categorize carbohydrates according to how many simple sugar molecules are joined together to form the carbohydrate. To test for the presence of monosaccharide, we will be using Clinistix (a product that is used to test for the presence of glucose in urine). See the label (in video) for details. These test strips are used by dipping the colored end into the solution, then comparing the color to the chart on the bottle. The positive color(s) is/are __________________________. The negative color is ________________.
