Chemical and Physical Processes of Digestion Lab Report Questions Activity 1 What is the difference between the IKI assay and Benedict’s assay? IKI assay detects the presence of starch‚ and the Benedict assay tests for the presence of reducing sugars as well as IKI turns blue black whereas Benedict is a bright blue that changes to green to orange to reddish brown with increasing levels of maltose What was the purpose of tubes #1 and #2? Why are they important? Because they are the controls

through hydrolysis. We used different methods to show how different tests involving heat‚ acid‚ saliva‚ and bacteria can hydrolyze polysaccharides and proteins. Through this experiment we have found that heat and acid hydrolyze starch while using the Benedicts test. Using the same test in a different manner showed how saliva has a big effect on the breakdown of polysaccharides. Using the IKI test we noticed bacteria like B.Cereus are able to digest starch polysaccharides‚ where as E.Coli does not‚ and

A positive outcome of the test results in a colour change; blue-black in the presence of starch and a red-brown in the presence of glycogen. A negative outcome results in no colour change and all solutions remain a very pale yellow (Pavia‚ 2005). Benedict ’s solution was used to identify the presence of reducing sugars; the aldehyde functional group is the part that reacts in the test. A positive indicator of the test is the formation of a coloured precipitate of the blue solution‚ ranging from yellow-green

Manukyan Ruth Benedict was considered a founding figure of American anthropologist and Benedict taught at Columbia University. Benedict was partially deaf. She has written many books‚ many of her books were published‚ and she is very well known. Benedict views social systems as communities with common beliefs. She believes that one system cannot be better than another. I agree with Benedict’s claim that morality is simply whatever a culture deems normal behavior. It is definitely a satisfactory

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

Crispin successfully allows the modern-day historian to delve into the medieval era and identify‚ firstly the detailed inner workings of an 11th century monastery. In addition to emphasising the continuity between what ‘St. Benedict’ rules and the way the monks lived.
