Villanueva - Biology Starch‚ Glycogen and Cellulose Independent Research A polysaccharide is a long chain of monosaccharide molecules‚ held by glycosidic bonds. They are usually not sweet in taste‚ insoluble in water and often do not produce crystals when water is taken out. Starch Starch is a complex solid carbohydrate‚ consisting glucose molecules held together by glycosidic bonds. It is a storage polysaccharide. They can be found in fruits‚ seeds‚ roots and other parts of the plant. The

Guide EXPLORE Part I: Testing Known Substances Teacher Prep: 1. Prepare and label four Erlenmeyer flasks and disposable pipettes with the following suggested solutions and place them in the front of the room for easy access for students: a. Polysaccharide Solution - blended potato or lab grade starch solution b. Monosaccharide Solution – apple juice or lab grade glucose solution c. Protein Solution – blended meat or egg whites d. Lipid Solution – vegetable oil‚ melted butter 2. Set up 4 lab stations

presence of starch. When starch is presence‚ the iodine lodges itself in the helical structure of the polysaccharide chain to give it a black blue colour. 2. Dilute Iodine was dripped onto a thin slice of potato to test for the presence of starch. Dark blue colouration forms on the potato slice indicating the presence of starch. The Iodine solution traps itself in the helical structure of the polysaccharide to form dark blue colour. 3. To test for the presence of glucose‚ Benedict’s solution was

Chemical Composition of Cells Testing for Proteins: The independent variable is the biuret reagent. The dependent variable is the solutions being used as follows; distilled water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was

PURPOSEThe purpose of the lab is to learn how to determine the presence of glucose‚ starch‚ lipid‚ and protein in various samples through standard tests. MODIFICATION1. Protein solution‚ vegetable oil‚ glucose solution‚ sucrose solution‚ starch solution and distilled water were added separately into six marked test tubes. The volume added was about one finger thick in depth of a test tube. 2. 5 drops of Iodine solution was added to each test tube. 3. The sample’s reaction with iodine was recorded
