  134. You have been assigned the task of constructing a protein. what type of building block would you use?
    Amino Acids

    Maltose
  136. Why is it necessary to shake an oil and vinegar salad dressing before adding it to a salad?
    To mix the oil into the water, albeit temporarily
  137. How would you test an unknown solution for sugars?
    Add Benedict's and heat
  138. How would you test an unknown solution for Fat?
    Is it soluble in water? on brown paper? with emulsifiers?
  139. How would you test an unknown solution for starch?
    Iodine (IKI) test
  140. How would you test an unknown solution for protein?
    Biuret's test
  141. Assume that you have tested an unknown sample with both biuret solution and Benedict's solution and that both tests result in a blue color.  What have you learned?
    Unknown contains no protein and no sugar.
  142. What purpose is served hen a test is done using water instead of a sample substance?
    Water serves as a control to compare other sample substances against.
  143. A test tube contains starch, hydrochloric acid, and water.  The biuret test is negative. Explain.
    No protein
  144. A test tube contains starch, hydrochloric acid, and water.  The biuret test is negative. Explain...No Protein ...After 30 minutes, the Benedict's test is positive. Explain.
    HCL Broke starch down into its sugar sub-units
  145. A test tube contains albumin and pepsin. The test for protein is positive. Explain.
    Both albumin and pepsin are proteins
  146. Although pepsin is an enzyme that breaks down protein, a test for peptides is negative. Explain.
    Pepsin itself a protein; if it was to breakdown other proteins into polypeptide sub-units, then perhaps not enough time, or heat, or stirring was allowed.
