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 come to the fore to be close towhat 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 experiment an unknown solution for starch, you would learn to attain a standard curve graph, find the tend 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 analyse tubes. You will besides need a test tube for the unknown, and a test tube for the neat, which will be water. neighboring 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, accordingly the unknown. Use the spectrophotometer to then find the concentration and absorbance of each sample.

3. water system 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 feed a positive, we could put the table sugar finished a reaction that would go through the depolymerization pro cess. This would break the disaccharides i! nto monosaccharides, which would then be able to be detected by Benedicts Test.If you unavoidableness to get a full essay, order it on our website: BestEssayCheap.com
