Llab report on testing for macromolecules.

TESTING FOR MACROMOLECULES PURPOSE: To determine the presence of glucose, stiffen, lipids, and protein in various try ons. APPARATUS: ·Safety goggles ·6 graduate cylinders ·6 sample thermionic valves ·A sieve vacuum electron tube rack ·hot piss bath · political campaign tube brush · too large beaker ·40 mL protein closure ·40 mL vegetable vegetable oil ·40 mL malt sugar resolving ·40 mL sucrose stem ·40 mL starch root word ·40 mL distilled irrigate ·Benedicts resolve 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 · base towel PROCEDURE: PART A: 1. Hot water supply bath was set up by development specialty setting for the hot plate. 2.The half dozen receive cylinders were mark with egress 1 to6. 3.Six- study tubes were also marked with the public figure 1 to 6. 4.Protein solution was measured forth 10 mL and was poured into calibrated cylinder 1. 10 mL of vegetable oil was poured into receive cylinder 2, 10 mL of maltose solution into calibrated cylinder 3, 10 mL of sucrose solution into gradational cylinder 4, 10 mL of starch solution into graduated cylinder 5 and 10 mL of distilled solution into graduated cylinder 6. 5.The ladder 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 tryout tube. 7. any the test tubes were heat 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. raw the observations for each test tube were recorded, then the glassware was washed PART B: 1.Steps 3,4 and 5 were repeated from function A. 2.After that 5 drops of iodine solution was added to the test tube. 3.Contents of each test tube were carefully mixed. altogether the observations...
