Identifying Macromolecules Worksheet Answers
Terminology review: Controls Water plus Benedict's reagent is a negative control for the sugar test. It demonstrates a negative test result no sugar present. See tube 1 above. Glucose plus Benedict's reagent is a positive control for the sugar test. It demonstrates what a strong positive result should look like. It also proves that our reagents haven't gone bad they are capable of producing a positive result. See tube 4 above. The point of controls is twofold. They give you standards to compare against, and they demonstrate that your reagents are working correctly. Class Benedict's Reagent Results Aside from our controls, we tested three solutions for glucose: starch, acid-treated starch, and amylase-treated starch.

As starch is a polysaccharide, it is unsurprising that the starch solution tested negative for simple sugars. We mixed HCl an acid into starch and re-tested for simple sugars. First, we had to adjust the pH of the solutions back to neutral before adding the Benedict's reagent. We used a pH indicator and NaOH a base for this. We then added the Benedict's reagent. We got moderately positive results orangish color. This is because HCl breaks starch back down into its component monosaccharides glucose, in this case. Amylase is an enzyme that removes glucose molecules from starch. Both plants and animals use amylase when digesting starch. Unfortunately, amylase cannot break the beta-bonds which hold the glucose molecules together in cellulose. If it could, we'd be able to eat hay. Based on this information, can you figure out what our results should be if we tested amylase-treated starch and amylase-treated cellulose solutions for reducing sugars?
