Testing For The Presence Of Common Biological Macr

Testing for the Presence of Common Biological Macromolecules T distributivelyer Assistants: MH and SM Section 017 Cell Biology Wednesday at 9:30 am Experiment(s) performed Wednesday, September 21, 2011 Introduction The objective of this experiment was to blend familiar with tryouts for super acid biological macromolecules such as artless borecoles, complex sugars, and proteins. exclusively of the rivulets had expected results and were completed in order to confirm our predictions. 12 different substances were bear witnessed to be either a simple sugar, a complex sugar (such as glycogen) or a protein. A different test was used to test for sever ally macromolecule. Simple sugars (or bring down sugars) are sugars that can reduce Cu++ ions to Cu+ ions (BIOL 130L excrete 2011 Lab Manual, P. 17). Complex sugars such as glycogen and amylum are large enough to frame iodine and in turn change the firmness to bluish black in strain (BIOL 130L radiate 2011 Lab Manual, P .17). Protein is tested for by victimisation Cu++ ions which interact with the peptide bonds between the amino acids in a polypeptide and cause it to turn violet in colour (BIOL 130L Fall 2011 Lab Manual, P.16). Materials and Methods See BIOL 130L Lab Manual Fall 2011, p. 15-19 for materials and methods of this experiment. Results carry over 1: Substance List 1) 1% glucose consequence| 2) 0.

3% glucose-1-phosphate firmness| 3) 1% maltose solving| 4) Honey theme| 5) 1% sucrose reply| 6) 1% lactose solution| 7) 1% glycogen solution| 8) 1% starch solution| 9) Protein solution| 10) Beer| 11) Di! stilled water| 12) Unknown solution (#224)| Biurets test atomic number 11 hydroxide (NaOH) was added to each solution in the test tubes. Substances in all test tubes retain their original colour. Substance 9 developed bubbles on crystalise of the solution. Copper sulfate was added to each solution in the test tubes. Substances 1-8, 11 and 12 all turned blue. Substance 9 turned a shadowiness of violet. Substance...If you want to get a full essay, order it on our website: BestEssayCheap.com
