Basic Chemistry for investigating living things

Which trial thermionic valve represents the concord? The unmatched with water. C. why? When protein molecules are present, capital of Lebanon Reagent reacts with the protein to form a purple strain. subway system number one is the control underground because it is distilled water and has no protein the tube has no color. C. Which test tube reserveed the almost test magnetic core? Amylase D. separate than the control, which test tube contained the least test substance? Hard to assure because the other ones didnt remove much of a color, so it didnt seem ilk there was much protein at all. E. Did the results bind with your initial guesswork in every case? Yes F. Why or why to?starches and breads are helped by protein enzymes and Amylase is an enzyme. Good source of protein, so I thought Albumen would contract protein Eggs are a foods, besides the Beirut reagent isnt strong overflowing to pick up small amounts G. If the color depart is not as you expected, what facult y be the reasons? Contamination H. Add another 5 drops of Beirut Reagent to each test tube and stir as before. Do your results change? I didnt notice any change Discussion A. What is the purpose of this coif? To use color to obtain if substances have protein since Beirut reagent would react with a protein to form a purple color B.Why is it important to clean droppers and equipment amidst chemical uses? To avoid cross contamination C. What other types of foods or substances contain full(prenominal) levels of protein? Meat or fingernails D. Suggest a situation where you ability use the Beirut Reagent colorimetric test. It kidney disease E. What other types of analytic procedures detect the presence of proteins? The Lowry Method Exercise 2 Testing for the Presence of Starch in Cells A. What is the test substance? Starch B. Which test tube represents the control? Water C. Why? Water has no starch and it turned amber, so if your color was amber, you ad no starch D.Which test tube c ontained the most test substance? Potato starch Other than the control, which test tube contained the least test substance? Albumen and amylase E. Did the results agree with your initial hypothesis in each case, why or why not? know to have starch, and they did. I didnt expect the proteins Yes, potatoes are to have starch sources, but theyre not in every natural food source G. If the color change is not as you expected it to be, what might be the reasons? That items I did not think had starch, actually did have it. A. What is the purpose of this exercise? one reacts with carbohydrates to form a dark blue color, so you would know if the substance had carbohydrates based on the color it turned. B. What other types of foods or substances contain high levels of starch? Wheat grain C. Suggest a situation where you might use the iodine colorimetric test. Testing for thyroid issues D. What other types of analytical procedures detect the presence of starch? Detect the presence of starch by using the chemical method A. What is the test substance? Sugar C. Why? There is no sugar in water, and it turned a return blue.Any test with that color old mean that there was no sugar C. Which test tube contained the most test substance? Glucose D. Besides the control, which test tube contained the least test substance? Potato starch D. Did the results agree with your initial hypothesis in every case? Yes E. Why or why not? The test specifically looks for glucose, so other carbohydrates and starches that dont have glucose, go forth not show sugar F. What are you conclusions about the results? Glucose will react with Benedicts reagent G. If the color change is not as expected, what might be the reasons? Contamination
