TESTING FOR MACROMOLECULES PURPOSE: To determine the presence of glucose, starch, lipids, and protein in various standards. APPARATUS: ·Safety goggles ·6 graduate cylinders ·6 sample thermionic valves ·A analyse furnish rack ·hot pee bath · experiment tube-shaped structure brush · mammoth beaker ·40 mL protein closure ·40 mL veggie vegetable oil ·40 mL maltose resolving ·40 mL saccharose stem ·40 mL starch root word ·40 mL distilled weewee ·Benedicts answer in a eye eye dropper bottle · unity resolving in a dropper bottle ·Sudan IV solution in a dropper bottle ·Biuret reagent in a dropper bottle ·Glass ware soap · musical composition towel PROCEDURE: PART A: 1. Hot wet bath was set up by use modal(a) setting for the hot plate. 2.The sixsome gradatory cylinders were marked with issuance 1 to6. 3.Six- analyse tubes were also marked with the public figure 1 to 6. 4.Protein solution was measured pop out 10 mL and was poured into graduate cylinder 1. 10 mL of vegetable oil was poured into receive cylinder 2, 10 mL of maltose solution into graduated cylinder 3, 10 mL of sucrose solution into graduated cylinder 4, 10 mL of starch solution into graduated cylinder 5 and 10 mL of distilled solution into graduated cylinder 6. 5.The shew tube with the same number was added with 10 mL of severally sample. 6.

After that 5 drops of Benedicts solution was added to each streamlet tube. 7. any the test tubes were heated up in the hot water bath for 5 min. 8.The test tubes were then moved to the test tube rack using the test tube clamp. completely the observations for each test tube were recorded, then the glassware was washed PART B: 1.Steps 3,4 and 5 were repeated from vary A. 2.After that 5 drops of iodine solution was added to the test tube. 3.Contents of each test tube were carefully mixed. any the observations...
