Chemistry of Life: Macromolecules
Polymer Principles, Carbohydrates and Lipids
Carbohydrates – energy and building material
Lipids – diverse hydrophobic molecules
1
, Learning Objectives
Understand the concepts of monomer and polymer
Understand dehydration and hydrolysis reactions
Carbohydrates
Classify carbohydrates, provide an example of each and state their role
(fuel and/or structure).
Know that dehydration reactions form covalent bonds between
monosaccharides, glycosidic linkages.
Lipids
Know the three important groups of lipids: fats, phospholipids, and steroids
and describe their biological importance.
Distinguish between a saturated and an unsaturated fat and identify the
emergent properties that are a consequence of these structural
differences.
Why learn about chemistry in a biology course?
Organisms are made up of chemicals and undertake chemical reactions (metabolism) to survive.
Understanding key characteristics of each macromolecule group assists in understanding cells (and human digestion).
