Lab #1 Extraction and Thin Layer Chromatography Kaya Gaudet 6784928 January 9‚ 2013 Line Structure References BenzophenoneBiphenylBenzoic Acid Extraction: A process used to separate different compounds in a mixture based on their solubility in an immiscible substance. Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities

This lab report is not perfect‚ but can serve as a guide in understanding how to write one! Introduction Insulin‚ an amino-acid based protein‚ helps make up a larger polypeptide chain‚ proinsulin‚ which is located within the beta cells of the pancreas. Enzymes release the insulin from the larger proinsulin chain just before it is secreted from the beta cells. Insulin’s main function is to lower blood glucose levels by speeding up the membrane transport of glucose from the blood and into

Enzyme Lab Daniyal Abdali (Rachel Lee) (Sarina Dolch) SBI 3UI Mr. Vrabec October 20‚ 2009 Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations

solution set is {5}. In the second solution set both sides of the equation must be equal. Equal means that both sides are balanced. The equality of addition property states that each side of the equal sign must have the exact same numerical value. On both sides‚ we have a which is the same “number” or “letter”. Since 5 is on one of the sides 5 must be on the other side due to the equality of addition property. That makes x {5}. Finally‚ because both of their solution sets are {5}‚ we know that
