 Also called condensation polymerization  Polymers are formed when water is “removed” from monomers Remove HO H H Water Create

 Polymers are split into monomers when water is “added” Water HO H H Break Apart

 Review: carbohydrates from food provide energy (calories) that can be released rapidly (minutes to hours)  The larger the carb, the longer the energy will last Short carb, short energy Long carb, long energy

 Proteins contain about the same amount of energy as carbs  Protein in food can be broken down for energy OR used to build new things  Proteins already being used in the body (muscles, organs, etc.) are only broken down as a last resort

 Lipids contain more than twice as much energy as carbs or proteins  May be broken down right away or stored for later use 1 Gram of Carbohydrate 1 Gram of Protein 1 Gram of Lipids 4 Calories 9 Calories
