1. What is an anabolic reaction? Catabolic reaction?
Agenda for Thursday Nov 3rd
Food Label activity
Finish Macromolecule notes
Quiz tomorrow

2. Macromolecules Large molecules created by joining smaller molecules
Bike chain
Polymer – molecules formed by repeating units of monomers
4 major categories: Carbohydrates, lipids, proteins, nucleic acids

3. Carbohydrates Carbon, hydrogen, and oxygen
Ratio of 1 C, 2 H, and 1 O
Supply most of the energy for your body
Play important health-promoting roles
Digestion, absorption, eliminate toxins/waste

4. Types of Carbohydrates
Monosaccharides –1 unit
simple sugars
immediate energy
Fruits and honey

5. Types of carbohydrates
Disaccharides – 2 monosaccharides linked together (2 units)
"simple sugars"
Includes lactose (milk), sucrose (table sugar), maltose (starch)
similar to monosaccharides; provide sweet taste to food and quick energy

6. Carbohydrates Polysaccharides – longer carbohydrate chains
Complex carbohydrates
Starch, Fiber and Resistant Starch
Digestion takes longer
Extended/sustained source of energy

7. Why are carbohydrates important for our body
Why are carbohydrates important for our body? List some carbohydrates you may purchase in the store.

8. Lipids Carbon and hydrogen Store energy Unsaturated, or saturated
Fats, oils, waxes
Store energy
Unsaturated, or saturated
Hydrophobic – does not dissolve in water
Serves as a barrier

9. Lipids Saturated fats are straight molecules Unsaturated fats
solids at room temp.
butter and fats found in meat
Unsaturated fats
are liquids at room temperature
olive oil
in oils from grains and seeds, such as flaxseed oil

10. Lipids and You Cell membranes contains different kinds of fats
keeps membrane flexible and moveable
When saturated fats are too high, cell membranes become inflexible and don't function well
Body needs unsaturated fats
Cell membrane
Brain
Anti-inflammatory - arthritis

11. Proteins Constitute the majority of the structural tissue in your body
Bone, connective tissues, hair, muscles, skin, antibodies, hormones, enzymes
Proteins are involved in just about every function in your body
enzymes are proteins

12. Proteins Made of amino acids same structure with a variable group
20 different variable group

13. Proteins Need amino acids
Your body will begin to break down its own muscle
Stunting, poor muscle formation, thin and fragile hair, skin lesions, a poorly functioning immune system
You get the majority of your protein from nuts, legumes, eggs, fish, meats and dairy products

14. Nucleic Acids Store and transmit genetic information
Phosphate, sugar, and nitrogen base (nucleotide)
Nucleotides form together to create nucleic acid
DNA, RNA
Nucleotide with 3 phosphates is ATP
energy used by cells
In everything!
