Again, you would label seven small test tubes, If a liquid sample is they react with glucose to form precipitate that changes the color so we can identify it, what is the role of Cu++ ions in test 1? Based on the If a scientist turns a polymer into monomers in the laboratory, would the resulting material be larger or smaller than the starting reactants? If a change occurs in the second test with Benedicts Reagent, then non-reducing sugars are present. The antigen is then detected either directly (labeled primary antibody) or indirectly (such as labeled secondary antibody). Iodine will stain starch (a complex carbohydrate) a dark blue or black color and Benedicts will turn green, yellow, orange or red in the presence of various concentrations of simpler sugars (such as glucose). A) . immediately. I physically walk them through the entire process of coloring, cutting and pasting each monomer to create a structural representation of the polymers discussed. Positive and Negative Controls These nitrogen atoms combine with copper (II) ions and form a PURPLE complex. Testing an Unknown Substance There are 3 unknown food items labeled A B and C.
