Each test tube was filled with at least mL of one solution. Two students should prepare the controls 1L, and 2L,while the other two students in the group set up the experimental samples 3L to 5L, 4B, and 5B as indicated in Chart 3. Moreover a test for accuracy becomes difficult because it is not possible to find any errors due to incomplete digestion or loss of NH3 for the fact that a known sample was not used for analysis.
Stomach plays a vital role in the digestion. Salivary is most effective at a pH of 7. The copper II ions in the Benedict's solution are reduced to Copper I ions, which causes the color change.
The sample was found to contain The distillate was then titrated using the standardized NaOH solution.
Have students brainstorm sources of proteins, carbohydrates and fats in their diet. Both organic compound contribute to our lives, and our health is heavily dependent on them.
Or use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. You can use PowerShow. These important cells are made up of polymers of amino acids whose functional groups are a carboxyl group and a free amino group.
In which tube has emulsification occurred. Explain, based upon your results. Why is salt required to make ice-cream. Explain whether or not we can determine fat hydrolysis in tube 5. Use spoon and enjoy ice cream. ConclusionIn this experiment, the protein content of a sample of Old Fashioned Oats was analyzed by the Kjeldahl Nitrogen Analysis method.
Disaccharides are composed of two monosaccharides joined together.
Then, we filled each test tube with one designated solution. Reduced opyical density; decreased rate of enzymatic Plant oils can be turned into a solid form margarine, crisco by hydrogenating the fatty acids.
Describe the activity of lipase with and without the addition of bile salts. The different amino acids have different side chain, but are otherwise identical. Lastly, we recorded any color changes in our chart. In DNA deoxyribose nucleic acid the sugar is a deoxyribose and the nitrogenous bases are adenine, guanine, cytosine and thymine.
The fatty acid "tails" are long chains of carbon and hydrogen that contribute to the non-polar behavior of fats - they don't mix with polar water.
Cover each tube with a small square of Parafilm, shake vigorously, and allow the tubes to stand at room temperature. Digestion Lab Report: Digestion Lab: educationalvideo: Egg Cell Experiment. Ice Cream Lab. Questions: What is a physical reaction? What is matter?
