3. Sec 1: Properties of Carbon
KEY CONCEPTS
Because of its ability to combine in many ways with itself & other elements, carbon has a central role in the chemistry of organisms
The 4 forms of the element carbon are:
1) diamond
2) graphite
3) fullerenes
4) nanotubes
Mrs. Lee - Ch 8

4. Sec 1: Key Terms

5. Sec 2: Carbon Compounds KEY CONCEPTS
Many organic compounds have similar properties in terms of melting points, boiling points, odor, electrical conductivity, & solubility
Hydrocarbons mix poorly with water. Also, all hydrocarbons are flammable
Mrs. Lee - Ch 8

6. Sec 2: Carbon Compounds (cont’d)
The carbon chains in a hydrocarbon ring may be straight, branched, or ring-shaped. In addition to forming a single bond, two carbon atoms can form a double bond or a triple bond
If just one atom of another element is substituted for a hydrogen atom in a hydrocarbon, a different compound is created
Mrs. Lee - Ch 8

7. Sec 2: Carbon Compounds (cont’d)
Many esters have pleasant, fruity smells
Organic compounds can be linked together to build polymers with thousands or even millions of atoms

9. Sec 3: Polymers & Composites
KEY CONCEPTS
Polymers form when chemical bonds link large numbers of monomers in a repeating pattern
Many composite materials include one or more polymers
You can help reduce the amount of plastic waste by recycling
Mrs. Lee - Ch 8

10. Sec 3: Key Terms
Protein
Amino acid
Plastic
Composite
Mrs. Lee - Ch 8

11. Sec 4: Life with Carbon KEY CONCEPTS
The 4 classes of organic compounds required by living things are:
1) carbohydrates
2) proteins
3) lipids
4) nucleic acids
The energy released by breaking down starch allows the body to carry out its life functions
Mrs. Lee - Ch 8

12. Sec 4: Life with Carbon (cont’d)
The body uses proteins from food to build & repair body parts & to regulate cell activities
Gram for gram, lipids release twice as much energy in your body as do carbohydrates
When living things reproduce, they pass DNA & the information it carries to the next generation
Organisms require water, vitamins, minerals, & salts to help support the functioning of large molecules
