The purpose of this lab is to detect carbohydrates, proteins, lipids and nucleic acids in different compounds by performing several different tests, such as Benedict’s test, Iodine test for starch, Biuret test for protein, Sudan IV color test for lipids, grease spot test and the Dische Diphenylamine Test.
Most of the chemical compounds that are present in living organisms consist of covalently bonded carbon atoms. These compounds are organic compounds because they are either produced by living things or present in them. Organic compounds are important because they are major components of tissues and cells. They have many functions and purposes as they provide energy for life process, regulate metabolic reactions as well as transmit information. There are four important macromolecules that are essential to life and are essential for biological functions: Carbohydrates, Proteins, Lipids and Nucleic acids. Each of these macromolecules are made up of their perspective smaller subunits. The subunits of these macromolecules are held together by covalent bonds and each have unique structure and properties. So in this particular lab our goal is to find out how each besides nucleic acids, has different properties and how to test them using the tests and how to determine which macromolecule is present in which solution.
Another aspect of this lab is to gain a proper understanding of controls in biochemical tests and their significance. It is essential to understand the…
