Specific Objective: Carry out test for reducing sugar‚ non reducing sugar‚ starch ‚ protein and lipid. BIOCHEMICAL TESTS Reducing and non-Reducing Sugars Sugars can be classified as either reducing or non-reducing based on their ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. Reducing sugar have contain free aldehyde or ketone group and have the ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. All monosaccharides are reducing

If a solution is pinkish purple‚ or purple‚ then the test for protein is positive. The test solution for starches is yellowish brown. If any substance that is yellowish brown when mixed with iodine‚ then the test for starches is

cation and anion analysis is that in anion analysis‚ a series of separations of the ions from one another is usually not the most efficient way to determine their presence. Instead‚ only some separations will be made‚ and the initial test solution will be used to test many of the ions. Refer to the flow chart at the end of the experimental directions as you proceed. First you will prepare and analyze a “known” solution which contains all six of the anions. Then you will analyze an “unknown” solution
