The Iodine Test Sor Starch

The purpose of this experiment was to use Iodine, Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose, 0. 3% glucose-1-phosphate, 1% maltose, honey, 1% sucrose, 1%lactose, 1% glycogen, 1% starch, protein, beer, distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was…

Total Carbohydrates Using the Phenol Sulfuric Acid Method

The standard curve of the unknown glucose solution was constructed in order to solve for the concentration of glucose in corn syrup and Gatorade samples. These calculations can be shown in the results section of the lab. Under proper conditions, the phenol-sulfuric method is accurate to ± 2% (Nielson 2010). This seems to be true with the %CV shown in Tables 2 and 3 in the Absorbance columns. However, the accuracy of the results is completely dependent on the accuracy…
