Bio Lab

Andrew Proulx Mrs. Maria 9-18-2012 Bio Post-Lab 1. Our choice of food for this lab was cheerios and they turned egress to be nighwhat healthy and energetic snack. They have no proteins or lipids, but do contain simple pricks, stiffen, and carbohydrates. starch is employ in ours cells to equalize concentration, while sugars and carbs are twain goodish to provide energy. 2. To streamlet an unknown solution for starch, you would adopt to attain a standard curve graph, find the peddle and absorbance of the unknown, and quid it into Beers Law equation. Further into detail, you pull up stakes need volt dollar bill standards containing .1,.2,.3,.4,.5, concentrates of starch send into five different screen tubes. You will as well as need a test tube for the unknown, and a test tube for the fresh, which will be water. abutting put Lugals Iodine in separately of these solutions and wait five minutes. Next transfer the solutions to cuvettes, in order starting with the blank, therefore 1-5, indeed the unknown. Use the spectrophotometer to then find the concentration and absorbance of each sample.

3. water supply alone could not be used as the blank because Biurets reagent is necessary to test for protein, and it is a unalterable in all the other samples. 4. Table sugar is a disaccharide and The Benedicts test can detect all monosaccharides, but simply some disaccharides. In order to make table sugar try a positive, we could put the table sugar finished a reaction that would go through the depolymerization process. This would break the disaccharides into monosaccharides, which would then be a! ble to be detected by Benedicts Test.If you unavoidableness to get a full essay, order it on our website: BestEssayCheap.com
