BIOL 120 Fall 2006 Ch. 3 Learning Objectives Ch. 3 Macromolecules : Learning Objectives 1. List and briefly describe the four major macromolecules. In your descriptions make sure you understand the different categories and functions of each macromolecule and that you can describe several roles for each type of macromolecule. 2. Describe the chemical reactions required for the formation and breakdown of each type of macromolecule and be able to name the bond associated with polymers of each macromolecule. Macromolecule Polypeptide (protein) Nucleic Acid Polysaccharide (carbohydrates) Lipids Monomer Amino Acid Nucleotide Monosaccharide Fatty Acid Functions Structural support, protection, transport, catalysis, defense, regulation, and movement Storage, transmission, and use of information Two types DNA and RNA Energy storage and transport structural components. Carbon skeletons C molecules w/ H and OH groups Basic formula: CH2O fats and oils Store energy phospholipids structure Bonds Covalent in primary Hydrogen bonds at second tertiary Quat ionic Double covalent bond Covalent Nonpolar covalent hydrocarbons held by weak vander waal forces Formation Condensation Condensation Condensation Condensation Linkage Peptide Phosphodiester Glycosidic Ester 3. List the modifications that can be applied to carbohydrates, be able to name the carbohydrates emphasized in lecture and be familiar with the numbering of carbon atoms. The modifications that can be applied to carbon are glucosamine and galactosamine when amino groups substitute OH groups 4. Illustrate the difference between saturated and unsaturated fatty acids. Saturated is a straight carbon change is single bonded and can pack tightly Unsaturated has kinks and double bonds 5. Apply your knowledge of lipid biology to explain the orientation of phospholipids in a cell membrane. Lipids have hydrophilic heads and hydrophobic tails 6. Label the three main components of a nucleotide and be familiar with the different categories of base molecules utilized to produce nucleotides. Ribose or deoxyribose, base, and nucleoside Pruines are Adenine, Gunine Pyrimidines are Cytosine, Thyine, and Uraci
