1. Chemistry of Life

2. Matter Chemistry: study of matter Matter: any thing that has mass
3 phases: solid, liquid, gas
Both living organisms and non living things are made up of matter

3. Atom The atom is the basic unit of matter
Atoms contain :electrons, protons, neutrons and
There are different types of atoms
An element is a substance that is made up of the same type of atoms

4. Elements Elements are arranged in the periodic table
5 most common elements in the human body are
Carbon
Phosphorous
Hydrogen
Oxygen
Nitrogen

5. Atomic Number
The atomic number is the number of protons an atom has

6. Atomic Mass
Atomic mass is the number of protons plus the number of neutrons

7. Carbon
Carbon is the basic element found in living organisms.

8. 2 types of Chemistry
Inorganic chemistry: studies non-living, (non-carbon based) matter
Organic chemistry: studies matter with carbon

9. Molecule Two or more atoms join to form a molecule
Same type of atom: H2
Different types of atom: H20

10. Inorganic Molecules Do not contain carbon Not made by living organisms
Sodium Chloride
Water

11. Organic Molecules
Contain carbon
Made by living organisms
sugar

12. Macromolecules large organic molecules
Macromolecules and water provide the basis for living things

13. Macromolecules (cont)
Provide & store energy
Help regulate chemical
reactions necessary for life
Store & pass on genetic code

14. 4 basic groups of Macromolecules
Carbohydrates
Proteins
Lipids
Nucleic acids
