Chemical Composition of Cells: Experiment Instructions (Lab Report) LEARNING GOALS By the end of this unit, you should be able to do the following: 1. Describe the difference between organic and inorganic chemicals. 2. Relate oxygen content of a chemical to whether it is hydrophilic or hydrophobic. 3. Explain the relationship between starch, fiber, and complex carbohydrates and how they relate to glucose, sugar, and simple sugars 4. Describe how to use iodine, Benedict, and Biuret tests to identify starch, simple sugars, and protein respectively. 5. Describe the color of a positive reaction and a negative reaction for iodine, Benedict, and Biuret tests. 6. Describe how an emulsifier changes the mixing of oil and water. 7. Identify the Independent, Dependent, and Control Variables in your experiment. MATERIALS NEEDED 1 bottle of iodine (Get "Iodine Tincture" or Betadine antiseptic in the pharmacy section. DO NOT use decolorized iodine.) l bottle of blue or green food coloring 1 small potato 1 small onion 1 leaf of lettuce 1 stick of butter egg yolk

Explanation / Answer

1)

Organic compounds Inorganic compounds Contains carbon atoms and makes carbon-hydrogen bonds. They are therefore called as hydrocarbons. Does not contain carbon-hydrogen bonds Found in living matter like animals and plants Found in non living matter Form covalent bonds Form ionic bonds Lower melting and boiling points Higher melting and boiling points Insoluble in water and soluble in organic solvents. Examples are nucleic acids, enzymes, fats, sugars and proteins. They are soluble in water and insoluble in organic solvents. Examples are calcium, sulphur, iron, sodium etc.
