1. Which one doesn’t Belong?

2. Organic Molecules

3. 2.3.1 Organic Molecules make up living Things
Organic compounds: compounds that are found in living organisms and contain carbon. (there are some inorganic molecules with carbon in them like C02)

4. There are 4 Main types of Organic Molecules
Carbohydrates
Made of sugar monomers
Lipids
Made of fat monomers
Proteins
Made of amino acid monomers
Nucleic Acids
Made of nucleotide monomers

5. Amino Acids Make proteins
Proteins are involved or create the following:
Muscle structure
Hormones
Antibodies
Hemoglobin
Membranes

6. Lipids Hydrophobic molecules Major uses Fats Steroids Hormone Waxes
Membrane formation

7. Lipid (Fatty Acids) Long Hydrocarbon chains Oils and Fats
Saturated (maximum number of Hydrogens)
Butter, meat, cheese
Unsaturated some Carbons are double bonded
Avocado, olive oil, fish 3

8. Carbohydrates
Sugars
Used for cellular respiration
Maintain homeostasis
Kept in blood (glucose) for immediate energy
2 kinds
Monosaccharide's – one ring or one long chain
Disaccharides 2 rings
In sugars, every Carbon has an oxygen attached to it

9. Nucleic Acids Single and double ring molecules that contain Nitrogen
RNA or DNA
Different sugars attached to them
Stores your genetic information

10. Amino Acids

11. Carbohydrates

12. Fatty acid (in this case, palmitic acid)
Figure 5.10
Fatty acid (in this case, palmitic acid)
Glycerol
(a) One of three dehydration reactions in the synthesis of a fat
Ester linkage
(b) Fat molecule (triacylglycerol)

13. Nucleic Acids

14. Roles of Lipids
Long term storage (fat in animals, oils in plants)
Insulation
Buoyancy

15. 3.2.7 Compare energy storage of carbs vs lipids
Carbs short term / lipids long term
Carbs soluble (easy transport)
Lipids lighter weight, more energy per gram
