E N D
1. Inorganic vs. Organic Molecules
2. Organic Molecules Chemical compounds that contain a carbon backbone
Considered to be of biological origin- formed by a living thing
Lipids, Proteins, Nucleic Acids, Carbohydrates
3. Inorganic Molecules Molecules that do not contain a carbon backbone and are not formed by living things
Still important to life
Examples:
CO2
H2O
O2
4. There are four groups of organic compounds found
in living things…
1. Carbohydrates
2. Proteins
3. Nucleic Acids
4. Lipids
5. Carbohydrates Consists only of carbon, hydrogen, and oxygen (1:2:1)
Living things use these as main source of energy
6. Lipids Made mostly from carbon and hydrogen atoms.
Used to store energy.
Also important parts of biological membranes and waterproof coverings.
7. Nucleic Acids Contain hydrogen, oxygen, nitrogen, carbon, and phosphorus.
A bunch of nucleotides chained together.
Store and transmit genetic information.
8. Proteins Contain nitrogen as well as carbon, hydrogen, and oxygen
Amino acids chained together
Control the rate of reactions and regulate cell processes. Used to form bones/muscles. Transport substances into or out of cells or help fight disease.
9. Which is which?

A = lipids
B = nucleic acids/ nucleotides
C = proteins/ amino acids
D = carbohydrates/glucose
