Macromolecules Study Guide Answers
Macromolecules 2 Macromolecules Smaller organic molecules join together to form larger molecules macromolecules 4 major classes of macromolecules: carbohydrates lipids proteins nucleic acids 3 Polymers Long molecules built by linking chain of repeating smaller units polymers monomers = repeated small units covalent bonds 4 How to build a polymer Condensation reaction dehydration synthesis joins monomers by taking H 2 O out 1 monomer provides OH the other monomer provides H together these form H 2 O requires energy & enzymes. 13 Building sugars Dehydration synthesis monosaccharides disaccharide glucose glucose maltose glycosidic linkage 14 Other examples: Sucrose = glucose + fructose Maltose = glucose + glucose Lactose = glucose + galactose 15 Polysaccharides Polymers of sugars costs little energy to build easily reversible = release energy Function: 1. Energy storage starch (plants) glycogen (animals) 2.

Building materials = structure cellulose (plants) chitin (arthropods & fungi) 16 POLYSACCHARIDES many sugars Ex: STARCH polymer of αlpha glucose linked by α 1-4 glycosidic linkages Function: Energy storage in PLANTS Most animals have the enzymes to hydrolyze starch, too.
