3-1: Carbon Compounds

1. Carbon Bonding Organic Compounds: made primarily of carbon atoms Inorganic compounds do not contain carbon atoms (some exceptions)

1. Carbon Bonding (cont) Carbon atoms have unique bonding properties A carbon atoms has FOUR electrons in the outer most level So it can form four covalent bonds with other atoms Carbon Video

1. Carbon Bonding (cont) Carbon-based molecules have three general types of structures a. Straight chain b. Branched chain c. Ring

2. Large Carbon Molecules Monomers: smaller, simpler molecules Polymers: molecule of consisting of repeating units of monomers Large polymers are called macromolecules Draw and LABEL this image on the Left Column

2. Large Carbon Molecules (cont) Monomers link to form polymers through a chemical reaction called condensation reaction Every time a monomer is added a water molecule is released

2. Large Carbon Molecules (cont) Polymers are broken down through a process called hydrolysis. Water is used to break the bond between each monomer

3. Energy Currency Life processes require a constant supply of energy Andenosine Triphosphate (ATP) is a compound used to store energy in cells The hydrolysis of ATP is used to create energy for the cell.
