Chapter 5 notes The structure and function of Macromolecules Concept 5.1 Polymer: a long molecule consisting of similar or identical building blocks - like a train with many cars - monomers: repeating units that are the building blocks Diversity of life is based around 40 or 50 polymers Concept 5.1 Monomers are connected together by dehydration synthesis (anabolic) - covalent bond w/ the loss of H2O Polymers are broken down by hydrolysis (catabolic) - reverse rxn. of dehydration synthesis - ?break with water? Concept 5.1 Dehydration removes a water molecule, forming a new bond Short polymer Unlinked monomer Longer polymer Dehydration reaction in the synthesis of a polymer HO HO HO H2O H H H 4 3 2 1 1 2 3 (a) Concept 5.1 Hydrolysis adds a water molecule, breaking a bond
