CHEM 120 Introduction To general Organic, And Biological Chemistry with Lab week 7

Document Content and Description Below

Laboratory 10: Building models of Biological Macromolecules Learning Objectives:  Gain a better understanding of the structure and composition of biological macromolecules such as proteins, lipi... ds and carbohydrates  Gain an understanding of how structure impacts function  Learn to identify key functional groups present in biomolecules The functions of our bodies depend on macromolecules such as proteins, carbohydrates, lipids and nucleic acids. The structures of these macromolecules are crucial for their functions. In this lab, we will use a molecular modeling kit to learn about composition and structural formulas of functional groups and biological macromolecules. Note to Students: Read the lab before coming to class. The expectation at Chamberlain (CCN/CU) is that you come to class fully prepared for lab. Materials: Molecular modeling kit Exploration 1: Functional Groups Functional groups are made of specific elements and have a specific arrangement of atoms in space. Functional groups modify chemical properties of the hydrocarbon they are attached to. For example, when a hydroxyl group is added to the hydrocarbon ethane, the resulting compound ethanol or ethyl alcohol is more polar than the parent molecule ethane (tastes better too). Build the models of the following functional groups. Draw their extended structural formula. Show the models of functional groups to the instructor and obtain his/her signature before moving to the next [Show More]
